Mouse anti Human HLA B27 antibody, clone HLA-ABC-m3 recognizes the HLA-B27 alloantigen and reacts with the peripheral blood lymphocytes of 47/47 individuals conventionally typed as HLA-B27 + and precipitates cell surface molecules of 43 and 12 kDa, corresponding to the HLA Class 1 heavy chain and beta 2 microglobulin.

Scatchard affinity analysis shows that Mouse anti Human HLA B27 antibody, clone HLA-ABC-m3 has a higher affinity for HLA-B27 (9.7 x 108M-1) than for HLA B7 (9.5 x 107 M-1).

Flow cytometry - subjects expected fluorescence intensity:
Heterozygous HLA-B27+ = Strong.
Homozygous HLA-B27+ = Strong.
Heterozygous HLA-B7+ = Faint.
Non B27, Non B7 = Negative.
