Experimental Methods
1.Take 100mul peripheral blood anticoagulated by EDTA and add to the bottom of 5ml tube;
2.Add 10mul labeled antibody to the bottom of flow tube mixing with the whole blood, incubate for 20 minutes at room temperature away from light;
3.Add 2 ml1×RBC lysis buffer, incubate for 10 minutes away from light after mixing, dissolve red blood cells (recommended: RBC lysing Solution 10×);
4.Sample tube is set to 1000 rpm centrifugation for 5 minutes, discard the supernatant;
5.Add 2 ml PBS wash buffer to resuspend the cells, then1000 rpm centrifugation for 5 minutes, discard the supernatant;
6.Add 0.5 ml PBS wash buffer to resuspend the cells and detect by flow cytometry (sample should be determined on the day on the machine and can also be added fixation overnight at 4 degree C then measured).
[PBS wash buffer: PBS +1% FBS +0.1% NaN3]

anti-CD21 antibody
4ABU32 reacts with CD21 protein, a 145 kDa receptor for C3d complement fragment and for Epstein-Barr virus (EBV), expressed on all mature B lymphocytes from sIg+ stage, then lost upon activation. It also present on follicular dendritic cells and some epithelia cells. It is reported CD21 weakly expressed on the subset of mature T-cells. CD21 plays a role in B cell activation and proliferation and is part of a large signal-transduction complex containing CD19, CD81and other molecules as regulator of complement activation.This clone is cross reactive with non-human primate.*CD21 is a phenotyping marker of lymphoma.
