Summary and Explanation:
Progesterone Receptor (PGR) content of breast cancer tissue is an important parameter
in the prediction of prognosis and response to endocrine therapy (5). Studies have
shown PGR clone 16 is directed against the human progesterone receptor molecule (1
-5). A prokaryotic recombinant protein, corresponding to the N-terminal region of the
A form of human progesterone receptor, was used as the immunogen. Antibody
characterization studies demonstrated that PGR clone 16 reacts with both A and B
forms of human progesterone receptor by Western blotting procedure (4).

Technical Note:
This antibody has been optimized for use with Biocare's MACH 4 Universal HRPPolymer Detection and ONCORE HRP Detection. Other Biocare polymer detection
kits may be used; however, users must validate incubation times and protocols for their
specific application. Use TBS for washing steps.
This product is provided for Research Use Only (RUO) and is not for use in diagnostic
procedures. Suitability for specific applications may vary and it is the responsibility of
the end user to determine the appropriate application for its use.
1. This antibody contains less than 0.1% sodium azide. Concentrations less than 0.1%
are not reportable hazardous materials according to U.S. 29 CFR 1910.1200, OSHA
Hazard communication and EC Directive 91/155/EC. Sodium azide (NaN3) used as a
preservative is toxic if ingested. Sodium azide may react with lead and copper
plumbing to form highly explosive metal azides. Upon disposal, flush with large
volumes of water to prevent azide build-up in plumbing. (Center for Disease Control,
1976, National Institute of Occupational Safety and Health, 1976) (6)
2. Specimens, before and after fixation, and all materials exposed to them should be
handled as if capable of transmitting infection and disposed of with proper precautions.
Never pipette reagents by mouth and avoid contacting the skin and mucous membranes
with reagents and specimens. If reagents or specimens come in contact with sensitive
areas, wash with copious amounts of water. (7)
3. Microbial contamination of reagents may result in an increase in nonspecific
4. Incubation times or temperatures other than those specified may give erroneous
results. The user must validate any such change.
5. Do not use reagent after the expiration date printed on the vial.
