Dan-
My flow cytometry experience at Caltech taught me that many mouse
monoclonals bind very well, though non-specifically to lymphocytes.
The best results I got was to block the non-specific binding with an
initial incubation in 1:10 normal mouse serum and inclusion of the same
in each of the antibody cocktails which follow. Good luck!
