Ar. Ruiz et al., Influence of sample storage time and temperature on lymphocyte subset counts using a FACScount system, HAEMATOLOG, 85(5), 2000, pp. 550-551
We report the influence of storage and temperature on the count of lymphocy
te subsets from HIV positive patients using a FACSCount flow cytometer. The
results show that the quality of the counts remains high in the samples fi
rst stained and then stored for 24 hours, preferably at 4 degrees C.
