title: A radioimmunoassay for antibodies against surface membrane antigens using adhering cells.
abstract: A radioimmunoassay using cells adhering to plastic is described. In this assay, A-10 mammary carcinoma attached to the surface of plastic in microtiter plates were permitted to bind antibody and the bound antibody was detected with purified rabbit 125I-anti-mouse-Fab. The bound radioactive material was eluted with glycine-HCI buffer (pH 2.5), and the acid eluates were counted in a gamma counter. This assay can be used to detect cytolytic or noncyctolytic antibody to cell surface antigens in studies with any tumor or normal cell that will adhere to a solid surface.
