Brief History of HLA Testing in the Clinical Laboratory
“To date, HLA has been primarily thought of as a group of antigens. However, as understanding of antigen/antibody interactions has progressed, HLA perhaps should be recognized as a grouping of epitopes. An epitope is defined as the region of an antigen to which an antibody binds (Figure 3). Each antigen can have multiple epitopes; conversely, a single epitope may be present on multiple antigens.” MORE
