Flow crossmatch protocol
WebFlow cytometry crossmatching (FC-XM) is the most sensitive cell-based method for detecting donor-specific antibodies in clinical organ transplantation. Unfortunately, background FC-XM reactivity is elevated in assays with B lymphocytes-partly because of nonspecific immunoglobulin binding by Fc receptors and B-cell surface immunoglobulins. … WebThe flow cytometric lymphocyte crossmatch is a standard technique for evaluating the compatibility of potential kidney transplant recipients and donors. Recipient serum is incubated with donor lymphocytes and the latter are analysed in a flow cytometer for the presence of bound IgG antibodies. An increase in the level of IgG binding compared to ...
