A simple method for screening human T and B lymphocyte alloantibodies
An sRBC-hemolysin monolayer was employed for separating human lymphocytes into two sub-populations, adherent cells (predominantly B cells) and non-adherent cells (predominantly T cells). The separated cells were then tested simultaneously against predispensed sera by complement-mediated cytolysis for the presence of alloantibodies to either T or B cells. A total of 372 sera were screened. Antibodies specific for B cell antigens were found in 19 sera and 9 sera were found to contain antibodies to T-specific antigens.
