B. The positive control contains high concentration of the target DNA. Therefore, be careful during
the dilution in order to avoid contamination.

1. Intended Use
Leukemia BCR-ABL Fusion Gene(μ-BCR) real time RT-PCR Kit is used for the detection of
micro(μ) BCR-ABL gene variants (e19a2) in leukocyte by using real time PCR systems.
2. Principle of Real-Time PCR
The principle of the real-time detection is based on the fluorogenic 5’nuclease assay. During the
PCR reaction, the DNA polymerase cleaves the probe at the 5’ end and separates the reporter dye
from the quencher dye only when the probe hybridizes to the target DNA. This cleavage results in
the fluorescent signal generated by the cleaved reporter dye, which is monitored real-time by the
PCR detection system. The PCR cycle at which an increase in the fluorescence signal is detected
initially (Ct) is proportional to the amount of the specific PCR product. Monitoring the
fluorescence intensities during Real Time allows the detection of the accumulating product without
having to re-open the reaction tube after the amplification.
3. Product Description
The BCR-ABL fusion gene is associated with formation of the Philadelphia chromosome (Ph) and
is one of the most common genetic abnormalities detected in leukaemia’s. In the vast majority of
patients, the breakpoints in the BCR gene are clustered within three well defined regions. One
fusion gene called μ-bcr ,it is ver rare. The breakpoint located in the bcr region, resulting in an
e19a2 fusion transcript, which encodes for a longer 230 kDa BCR-ABL protein. e19a2 CML has
been associated with chronic neutrophilic leukaemia (CNL).Leukemia BCR-ABL Fusion
Gene(μ-BCR) real time RT-PCR kit contains a specific ready-to-use system for the detection of the
Leukemia BCR-ABL Fusion Gene(μ-BCR) using RT-PCR (Reverse Transcription Polymerase
Chain Reaction) in the real-time PCR system. The master contains Super Mix for the specific
amplification of -BCR. The reaction is done in one step real time RT-PCR. The first step is a
reverse transcription (RT), during which the Leukemia BCR-ABL Fusion Gene(μ-BCR) is
transcribed into cDNA. Afterwards, a thermostable DNA polymerase is used to amplify the specific
gene fragments by means of PCR (polymerase chain reaction). Fluorescence is emitted and
measured by the real time systems optical unit during the PCR. The detection of amplified
BCR-ABL fragment is performed in fluorimeter channel FAM. An external positive control
(1×108copies/ml) supplied, allows the determination of the gene load. For further information,
please refer to section 9.3 Quantitation.

7. Warnings and Precaution
Carefully read this instruction before starting the procedure.
• For in vitro diagnostic use only.
• This assay needs to be carried out by skilled personnel.
• Clinical samples should be regarded as potentially infectious materials and
should be prepared in a laminar flow hood.
• This assay needs to be run according to Good Laboratory Practice.
• Do not use the kit after its expiration date.
• Avoid repeated thawing and freezing of the reagents, this may reduce the sensitivity of the
test.
• Once the reagents have been thawed, vortex and centrifuge briefly the tubes before use.
• Prepare quickly the Reaction mix on ice or in the cooling block.
• Set up two separate working areas: 1) Isolation of the RNA/ DNA and 2) Amplification/
detection of amplification products.
• Pipets, vials and other working materials should not circulate among working units.
• Use always sterile pipette tips with filters.
Take positive control (1×10 copies/ml) as the starting high standard in the first tube. Respectively
pipette 36ul of Molecular Grade Water into next three tubes. Do three dilutions as the following
figures:
1)
The volumes of Super Mix and Enzyme Mix per reaction multiply with the number of
samples, which includes the number of controls, standards, and sample prepared. Molecular
Grade Water is used as the negative control. For reasons of unprecise pipetting, always add
an extra virtual sample. Mix completely then spin down briefly in a centrifuge.
2)
Pipet 15μl Master Mix with micropipets of sterile filter tips to each of the Real time PCR
reaction plate/tubes. Separately add 5μl RNA sample, positive and negative controls to
different plate/tubes. Immediately close the plate/tubes to avoid contamination.
3)
Spin down briefly in order to collect the Master Mix in the bottom of the reaction tubes.
4)
Perform the following protocol in the instrument:
45°C for 10 min, 1 cycle; 95°C for 15 min, 1 cycle; 95°C for 5 sec, 60°C for 30sec, 40 cycles.
Fluorescence is measured at 60°C;channel FAM should be chosen.
10. Baseline setting: just above the maximum level of molecular grade water.
11.Calabration for quantitative detection: Input each concentration of standard controls at the
end of run, and a standard curve will be automatically formed.
12.Quality control: The crossing point value of molecular grade water and positive control in
FAM channel shows blank and ≤35 respectively; Correlation coefficient of standard curve should
be ≤-0.98, otherwise the result is invalid.
13. Data Analysis and Interpretation
The following results are possible:
1) The crossing point value in channel FAM of μ-BCR Super Mix shows ≤38. The sample
contains micro(μ) BCR-ABL gene variants (e19a2).
2) The crossing point value in channel FAM shows 38~40, please repeat again. If the result still
shows 38~40,it can be considered negative.
3) In channel FAM no signal is detected. The sample does not contain any micro(μ) BCR-ABL
gene variants (e19a2). It can be considered negative.
