Crossmatch Testing with Selective Detection
Our FlowDSA-XM assay is a flow cytometry-based crossmatch assay optimized for the detection of leukocyte antibodies. Combining traditional flow cytometry cellular crossmatch testing with the specificity of microbeads technology, the FlowDSA-XM test selectively distinguishes leukocyte antibodies, allowing you to obtain selective detection in the first run.
FlowDSA-XM advances the science of crossmatch testing by combining traditional flow cytometry with microbead technology. Together, these proven technologies selectively distinguish human leukocyte antigen antibodies from autoantibodies, allowing you to obtain selective detection in the first run.
After incubating leukocytes with human serum, any bound IgG on the cell surface is tagged with PE labeled 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 human leukocyte antigen antibodies present in the serum.
