FlowDSA-XM™

FlowDSA-XM™ advances the science of crossmatch testing by combining traditional flow cytometry with the specificity of microbead technology. Together, these proven technologies selectively distinguish leukocyte antibodies from autoantibodies, allowing you to obtain selective detection in the first run.

After incubating lymphocytes with human serum, any bound IgG on the cell surface is tagged with PE labelled anti-human IgG. FlowDSA-XM Capture Beads bind selectively with the resulting antibody/antigen/PE-anti-IgG complex and the fluorescent intensity is measured to indicate the relative amount of leukocyte antibody present in the serum.
