Abstract

A method is described to identify specific antibody-forming cells and their immunoglobulin classes by a multilayer cluster formation. Cells producing specific antibodies are mixed with erythrocytes coated with the corresponding antigen in presence of rabbit anti-human immunoglobulins. Clusters are formed only if the mixtures contain rabbit anti-serum against the immunoglobulin chains of the specific secreted antibody. Thus the immunoglobulin class of the specific antibody is assessed. For this study the cells of three EBV-transformed, antibody-producing human lymphoblastoid cell lines were used.
