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. … WebEditorial The CDC crossmatch in the era of flow cytometric cross-match and single antigen beads.
