A Method of Increased Sensitivity for detecting Single Antibody-forming Cells


THE plaque techniques of Jerne et al.1 and of Ingraham and Bussard2 for assaying single antibody-producing cells involve the lysis of erythrocytes suspended in three dimensions around the active cells in a supporting medium, agar or methyl cellulose. Maximum sensitivity with this system would be expected if a single layer of lymphoid cells and target erythrocytes was examined. A method has been devised which dispenses with supporting media and allows detection of cells producing antibody sufficient to lyse only 10–20 adjacent erythrocytes.
