Rituximab and complement-mediated lysis of MCLs.
PBMCs from 6 cases of MCL were lysed with rituximab and 25% human serum (black bars) in the presence or absence of blocking anti-CD55 and/or anti-CD59 antibodies (10 μg/mL; hatched bars). Lysis was measured with the Alamar blue assay. The percentage CD20+cells in each sample is also shown (gray bars).
