Safety warnings and precautions
Acrylamide is a neurotoxin.
• Wear gloves when handling acrylamide or
polyacrylamide.
• Wear a dust mask when weighing acrylamide
or preparing acrylamide solutions.
Protecting your equipment
To keep your instrument in excellent condition,
please take the following important steps:
• Use water-saturated n-butanol for overlayering
resolution gels during polymerization.
Important! Most organic
solvents including methanol,
isobutanol, isopropanol, and
even n-butanol will craze or
cloud the acrylic plastic with
prolonged exposure. Only
use small amounts to overlay
the gels.
• pii
• Avoid using small metal spatulas to separate
the plates. Spatulas may chip the edges of glass
plates and prevent them from sealing.
• After casting, you may need to use a wedge
to separate one glass-and-gel sandwich from
another. Slip a Wonder Wedge in between
adjacent sandwiches to separate them.
Introduction
Gel sizes
The Hoefer™ SE 615 and SE 675 Multiple Gel
Casters are designed for casting vertical slab
acrylamide gels of homogenous or gradient
concentration.
Use the casters with 16 × 18 cm glass plates and
2 cm-wide spacers to cast 16 × 14 cm gels. Use
1-cm wide spacers to cast 16 × 16 cm gels for
two-dimensional electrophoresis. The resulting
gels are compatible with Hoefer SE 400, SE 600
and SE 600 Chroma Vertical Slab Gel Electrophoresis Units.
Homogeneous and gradient gels
The SE 615 and SE 675 can be used for casting
both homogeneous and gradient gels. Gradient
gels are cast through the port at the bottom of
the caster. When casting homogeneous gels, the
results are most consistent when the gels are cast
from the bottom. The V-shaped region at the
bottom of the casting unit allows the gel solution to rise evenly, producing identical gels.
• p1
Standard casting
In the standard casting procedure, a gel is cast
between two glass plates held apart by a pair of
spacers. (See Fig 2 on page 5.) The result can be
pictured as a “sandwich,” with the gel between
two glass plates. When you set up a vertical slab
gel electrophoresis unit, you place the glass and
gel sandwich in the electrophoresis unit.
The maximum number of gels you can cast
simultaneously using the standard casting procedure is shown in Table 1.1.

Casting with divider plates
You may find it useful to double the number of
gels run simultaneously in one electrophoresis
unit. This can be accomplished by casting a
“club sandwich.” A club sandwich contains a
notched glass divider plate and a second pair
of spacers between the standard plates, and
thus forms two layers of gel between three glass
plates (see Fig 3 on page 8.) Divider plates are
available for the SE 400 and SE 600.
The maximum number of gels you can cast
simultaneously, using divider plates (two gels
per sandwich), is shown in Table 1-2.

parts, accessories and related equipment, see
page 22.
Pouring second-dimension slab gels
When preparing second-dimension slab gels in
the multiple casters, it is important to pour the
slabs to the correct height.
If you are using IPG strips, you do not need a
stacking gel. Pour the second-dimension gel to
0.5 –1.0 cm below the top of the sandwich for
standard casting, or 1 cm below the notch if
you are casting with divider plates. This allows
ample room to hold the IPG strips between the
two glass plates. Use 1.0- or 1.5-mm spacers
with IPG strips.

Preparing the caster
1
If the faceplate is attached to the caster, remove it.
Remove the four side clamps, loosen the two thumb
screws, and slide off the faceplate.
2
Note: Do not block the red
inlet port at the bottom of
the faceplate.
Remove the foam cord gasket. Apply a light coat of
Gel Seal lubricant and replace the gasket.
3
When casting gradient gels, attach the tubing from the
gradient maker to the inlet port at the bottom of the
faceplate. Homogeneous gels may also be cast through
this port. If casting homogeneous gels from the top,
insert the appropriate displacement block in the open,
V-shaped region at the bottom of the chamber.
4
Place the open caster in a horizontal position with its
back on the bench top.
• p5
Building the stack
Note: To make separation of
polymerized gel sandwiches
easier, place wax paper sheets
in the caster between each set
of glass sandwiches.
Note: When analyzing a large
number of gels, you may find
it useful to include gel identification numbers into the
polymerized gel.
See the appendix on page 21
for directions on making gel
identification tags. Lightly
wet and place the tags in the
lower corner of the gel sandwich during stack assembly.
Note: If you use polycarbonate
sheets instead of wax paper
between each sandwich, the
caster holds fewer sandwiches.
1
Place a polycarbonate sheet in the caster so that 1/3
of the sheet extends out of the top.
You can use this sheet as a lever when inserting filler
sheets after all sandwiches are in place. All remaining
components fit flush against the bottom and sides.
2
Place a sheet of wax paper on the polycarbonate
sheet. Build the first sandwich into the caster.
3
Place a sheet of wax paper on top of the sandwich
and build the next sandwich.
4
Repeat step 3, alternating wax paper and gel sandwiches. Over the final sandwich, lay a polycarbonate
sheet instead of wax paper so that the gel solution
level is visible through the faceplate.
5
Place the faceplate on the caster and make sure the
stack fits snugly, about 0.5 mm above the edge of the
caster. If necessary, adjust the number of extra polycarbonate sheets, acrylic spacer blocks, glass plates
and sandwiches to obtain a snug fit.
6
Make sure the spacers are straight and along the
edges of the glass plates. Use the Spacer Mate to
correct the alignment if necessary.
If necessary, take the faceplate off and make sure all
edges of the stack components are flush. Press on
those that are sticking out until all edges are flush
and replace the faceplate on the caster.
7
Secure the faceplate with the four spring clamps and
tighten the bottom thumb screws.
• p6
Casting with divider plates
To double the number of gels run simultaneously
on the SE 600 and related units, place a notched
glass divider plate and another pair of spacers
between the standard glass plates. The result is a
“club sandwich,” with two layers of gel formed
by the three glass plates.
To use divider plates, follow the directions in
“Pouring standard homogeneous gels” on
page 9 or “Pouring standard gradient gels”
on page 11. When calculating solution volumes,
use the formula on page 9. When stacking glass
sandwiches, use the following procedure.
1
Stack glass sandwiches in the caster, using one club
sandwich for each two gels you will cast. Fill extra
space with acrylic blocks, glass plates and polycarbonate sheets.
2
Slide in one polycarbonate sheet against the back.
3
Slide in a glass club sandwich. (See Fig 3.)
To construct a club sandwich, slide in one rectangular
glass plate and place spacers along each of the two
side edges. Slide in a notched divider glass plate and
place spacers along each of the side edges. Finally,
slide in a second rectangular glass plate.
• p7
4
Place a polycarbonate sheet or wax paper on top of
the club sandwich.
Repeat step 3, alternating wax paper and club
sandwiches.
5
Note: For optimum visibility,
place a polycarbonate sheet
against the faceplate.
After the last club sandwich, add acrylic spacer blocks
and extra polycarbonate sheets until the entire stack is
approximately 0.5 mm above the rim of the box.

Prepare and degas enough monomer solution to fill all
sandwiches to the level of the notched plate.
The following formula allows extra solution to fill the
space between the sandwich and the chamber:
Monomer vol. = height × width × spacer
× total number of × 1.1
(ml)
(cm)
(cm)
thickness (cm)
gel sandwiches
Note: The 1.1 multiplier in
this formula assures enough
solution to fill dead volume.
No stacking gel. Fill solution to just below the top of
the notched plate. If air pockets form, remove with a
pipette or syringe. Introduce a comb, at a slight angle,
into each sandwich, taking care not to trap air under
the teeth.
Stacking gel. Fill solution to 4 cm below the top of the
rectangular glass plate. This height allows 1 cm of
stacking gel below the wells. Pour the gel and apply
an overlay. After the gel is set, prepare the stacking
gel as described on page 15.
2-D electrophoresis. Fill solution to about 1.0 cm
below the top of the rectangular glass plate. This
height allows 4 to 5 mm of space for the IPG strip
and an agarose seal. Overlay the separating gel as
described in step 3.
• p9
2
Caution! Isobutanol crazes
or clouds the acrylic caster
walls, making it difficult to
see the gels.
Add initiator and catalyst, and pour the solution into
the glass sandwiches from the top.
The solution flows from one sandwich to another
through the groove at the bottom of the caster and
rises to the same level in all sandwiches. Pour slowly
to avoid overfilling.
3
After reaching the final level, overlay each gel
sandwich with 300 µl of water-saturated n-butanol
or buffer.
Use the same amount of overlay on each gel sandwich
to assure that all the gels polymerize to the same
heights. Pour the liquid gently, taking care not to
disrupt the gel surface.
After polymerization is complete, remove the
n-butanol and replace it with buffer or add stacking
gel. Water-saturated n-butanol will cloud acrylic parts
if used in large amounts or for long periods.
4
Allow the gels to polymerize for at least an hour. To
remove the polymerized gels, see “Removing polymerized gels” on page 17. To add a stacking gel, see
“Pouring stacking gels” on page 15.
• p10
Pouring standard
gradient gels
See Fig 1 on page 4 for a diagram of the caster
components. See “Setting up the caster” on
page 5 for recommended solution volumes.
Setting up the gradient maker
1
Prepare a 50% glycerol displacement solution
containing a small amount of bromophenol blue:
approximately 75 ml for the SE 615 and 35 ml for
the SE 675.
2
Calculate the amount of gradient solution you will
need by referring to the formula on page 9.
For one-dimensional gels: Use a 12-cm separation
gel with a 4-cm stacking gel.
For two-dimensional gels using IPG strips: Calculate
the amount of solution needed to fill the sandwiches
to approximately 0.5 –1.0 cm below the top of
the plates.
3
Set up the peristaltic pump. Using a graduated
cylinder and water, adjust the flow rate so that the
volume of the gradient separation solution plus the
volume of the glycerol solution will be completely
delivered in 10 –15 minutes.
4
Choose a gradient maker that holds no more than
four times the total volume of gradient solution to
be poured. Check that the gradient maker is clean
and that the outlet and mixing port are free of
polymerized acrylamide.
• p11
5
Assemble the gradient components. (See Fig 5.)
a. Close all gradient maker valves and place a stir
bar in the mixing chamber, the one with the tube
connector port.
b. Attach one end of a piece of tubing to the outlet of
the gradient maker.
c. Run the other end of the tubing through the peristaltic pump and attach it to a tubing connector.
d. Use a second piece of tubing to attach the tubing
connector to the red inlet port at the bottom of
the caster.

Warning! Acrylamide is a
neurotoxin. Wear gloves when
handling acrylamide or polyacrylamide. Wear a dust mask
when weighing acrylamide or
preparing acrylamide stocks.
1
Prepare and degas the two monomer solutions for the
gradient maker.
Add glycerol or sucrose to the solution of higher
acrylamide concentration to stabilize the gradient as
the solution is pumped in. Decrease the concentration
of initiator so that polymerization occurs from top to
bottom. This minimizes convective mixing due to the
heat generated by polymerization.
2
Close both the mixing port and outlet port, if
appropriate, on the gradient maker. Clamp the tubing
from the outlet when using the SG 500.
3
Add initiator and catalyst, and immediately pour the
light (low concentration) acrylamide solution into the
mixing chamber—the chamber with the outlet port.
Open the mixing valve slightly to allow the connecting
channel to fill and force out air bubbles.
Close the valve again and pour the heavy (high concentration) acrylamide solution into the reservoir chamber.
4
Start the magnetic stirrer and unclamp or open the
outlet valve. Start the pump and open the mixing valve.
• p13
5
When almost all the acrylamide solution is drained
from the gradient maker, stop the pump and close
the mixing valve. Tilt the gradient maker towards the
outlet side and remove the last few milliliters of mix.
Do not allow any air bubbles to enter the tubing.
6
Add the glycerol displacement solution to the mixing
chamber and start the pump. Make sure no bubbles
are introduced. Pump until the bottom of the caster
is filled with displacement solution to just below the
glass plates, then turn off the pump. Clamp off the
tubing to the red inlet port of the caster.
7
Note: Isobutanol clouds the
acrylic, making it difficult to
see the gels.
Overlay each separate sandwich with 300 µl of watersaturated n-butanol or buffer.
Use the same amount of overlay on each gel to
assure that all the gels polymerize to the same height.
Carefully and gently pipette the liquid, taking care not
to disrupt the gel surface.
After polymerization, remove the n-butanol. Replace
it with buffer or add a stacking gel.
8
Allow the gels to polymerize for at least an hour.
To remove the polymerized gels, see “Removing
polymerized gels” on page 17. To add a stacking gel,
see “Pouring stacking gels” on page 15.
• p14
Pouring stacking gels
You may add stacking gels to the entire set of
polymerized gels —homogeneous or gradient—
while the sandwiches are still in the casting box,
or you may add stacking gel to individual gels
immediately prior to use.
For optimal resolution, add the stacking gel at
the last minute to prevent diffusion of buffers
between the two gel layers.
1
If you are pouring stacking gels later, skip to step 1
under “Removing polymerized gels” on page 17.
If you are pouring stacking gels now, calculate the
volume of stacking gel monomer solution needed by
referring to the following formula:
Monomer vol. = height × width × thickness × total number of
(ml)
(cm)
(cm)
(cm)
stacking gels
where
• Height is the distance between the separating gel
and the top of the plates
• Width is the distance between the spacers
2
Rinse off the water-saturated n-butanol overlay with
distilled water or Tris buffer and invert the caster to
drain it. Repeat this 2–3 times.
3
Degas the stacking gel monomer solution and add
catalyst and initiator.
• p15
4
Replace the caster in a vertical position. Make sure
the surface of the separating gel is free of liquid.
Use a pipette to fill each sandwich individually with
stacking-gel monomer solution.
5
Hold a comb, attached to a comb back, at a 45°
angle and centered within the sandwich. Insert one
end into the gel so that the end tooth is almost
completely inserted. Slowly lower the remaining comb
teeth in one by one, rotating the comb gradually
downward until it is in a horizontal position.
Refer to Fig 1 on page 4 for the final position of the
comb. Repeat this for each sandwich.
6
Note: Oxygen inhibits gel
polymerization. Do not trap
air bubbles underneath the
comb teeth.
Note: Use gels with stacking gels immediately. Do
not store.
• p16
Allow the stacking gels to polymerize for at least one
hour. To remove the polymerized gels, see “Removing
polymerized gels” on page 17.
Removing polymerized gels
1
After the gels have polymerized, place the caster in a
horizontal position. If you poured stacking gels, leave
the combs in place. Remove the faceplate.
2
Tip the caster to pour off the glycerol solution.
3
Note: The SDS buffer makes
the glass plates slippery.
Note: Do not use metal
spatulas to separate the sandwiches. Narrow metal spatulas
often chip the edges of glass
plates, making the plate
ineffective for sealing into the
electrophoresis tank.
Note: Separate the sandwiches
from one another before placing the gels in the refrigerator.
Slide the stack of sandwiches, acrylic blocks, and
polycarbonate sheets out of the caster. Remove the
acrylic blocks and polycarbonate sheets from the top
of the stack.
4
Carefully remove individual glass and gel sandwiches
from the stack. If necessary, insert a Wonder Wedge
between adjacent sandwiches to separate them.
Work slowly and cautiously when prying apart adjacent
sandwiches after polymerization.
5
Rinse the caster and polycarbonate sheets, as
described in “Care and maintenance” on page 20.
To store gels for future use
Rinse the individual sandwiches with distilled water.
Fill cassettes with gel storage buffer. Wrap gel sandwiches you are not using at this time in plastic wrap
and store them in the refrigerator.
To use gels immediately
1
Gently remove the combs by pulling them upward and
out of the gel sandwich.
2
Fill the wells with SDS Electrophoresis buffer.
3
Load samples and complete assembly. Refer to the
user manuals that come with SE 600 or SE 400
Series electrophoresis systems.

Appendix A: Gel identification numbers
For positive identification of gels, label each slab
by incorporating a small label printed on thin
filter paper in the bottom corner of the gel. Use
a carbon typewriter ribbon, photocopier or laser
printer to make these labels, since many liquidbased inks are electrophoresed off paper during
an SDS electrophoresis run.
A variety of numbering schemes are possible.
In our experience the easiest uses three parts
as follows:
• An upper-case letter to identify the investigator
or an extended gel series.
• A two- or three-digit serial number to identify
the slab gel batch.
• A lower-case letter to identify a gel in the
batch. Since a maximum of 14 gels can be
made in a batch, use the letters a–n.
The resulting numbers, in the format A63a,
A63b...., etc., provide a useful system for keeping track of and cross-indexing experiments and
gel production.
