Many years ago our lab played around with using AHG in the B-Cell cytotoxicity crossmatch, with mixed results. Some cells seemed to be overly susceptible to the reagent and had high cell-death backgrounds in all sera, while others did just fine. We’re planning to evaluate B-cell-AHG again, and would apprecaite hearing others’ experience and advice.

I think the main issue with B-Cell crossmatching is the CD32 receptors and the non-specific binding of IgG by the FcgR. Does your lab already do a B-cell Flow Crossmatch?

Yes, we perform a B-cell Flow XM, but there are some applications where our customers prefer a cytotoxicity crossmatch.
