Effect of time between completion of staining and data acquisition in the flow cytometer (0 h, 1 h, 3 h and 24 h) and the sample preparation protocol on the mean fluorescence intensity (MFI) of CD19-phycoerythrin cyanin 7 (PECy7), CD4-peridinin chlorophyll protein cyanin5.5 (PerCPCy5.5) and CD8-allophycocyanin hilite7 (APCH7) on peripheral blood (PB) B-cells, CD4+ T-cells and CD8hi T-cells, using ammonium chloride (a) or FACS Lysing Solution (b) as lysing reagents. Three different sample preparation protocols were evaluated: SLNW; SLW and SLWF. Results are shown as mean values (open circles) and 95% confidence intervals (vertical lines). FACS Lyse, FACS Lysing Solution; NH4Cl, ammonium chloride. SLW, stain-lyse-wash; SLWF, stain-lyse-wash-fix; SLNW, stain-lyse-no wash.
