STORAGE AND STABILITY
VersaLyse is stored between 18 and 25°C. If a vial of VersaLyse has been kept inadvertantly in a refrigerator, bring
it to room temperature (18 –25°C) and wait at least one hour before use.
With the vial closed, the reagent is stable up to the expiry date shown on the vial.
After opening, the reagent is stable for 90 days.
SAMPLES
Venous blood or bone marrow samples must be taken using sterile tubes containing an EDTA salt as the
anticoagulant.
NB: Carefully read in the ANTICOAGULANT section, the conditions under which other anticoagulants can be used.
The samples should be kept at room temperature (18 – 25°C) and not shaken. The sample should be homogenized
by gentle agitation prior to taking the test sample.
The samples must be analyzed within 24 hours of venipuncture.
WASHED SAMPLES
If you have to wash the samples before staining followed by lysis of the red blood cells, it is essential to remove
all the supernatant after the last centrifugation. An excess of washing buffer on the cell pellet can reduce the
effectiveness of VersaLyse.
PREPARATION OF SAMPLES
The concentration of leucocytes in the sample must be less than 10
4
cells / µL (10
10
/L). If necessary, dilute in PBS
to bring the leucocyte concentration to 5 x 10
3
/ µL (5 x 10
9
/L).
The erythrocytic concentration in the sample must be less than 6 x 10
6
/µL (6 x 10
12
/L), it is recommended to dilute
sample in PBS in order to bring the erythrocytic concentration to 5 x 10
6
/µL.
If both the leucocytic and erythrocytic concentrations need adjusting, the highest dilution must be used. The
procedures use 100 µL of a non-prediluted or pre-diluted sample per tube.
EVIDENCE OF DETERIORATION
Any change in the physical appearance of the reagents may indicate deterioration and the reagent should not be
used.
