Influence of anticoagulant. (A, B, C) CD11b expression on a sample with heparin anticoagulant. (D, E, F) The same sample but now collected in an EDTA tube. One noteworthy influence of EDTA anticoagulants on a sample is the change of expression patterns of specific antigen, such as CD11b. CD11b expression diminishes with EDTA (D and E) compared to heparin coated tubes (A and B).
