title: A direct antigen-binding assay to screen hybridoma supernatants.
abstract: A simple and convenient method of directly assaying hybridoma supernatants for the desired monoclonal antibodies is described which obviates the need for labeled second or third antibody conjugates. Culture supernatants (1-5 microliters) were directly spotted onto a nitrocellulose sheet, and additional protein binding sites blocked with bovine serum albumin and incubated with enzyme-labeled, radioactive, or fluorescent antigen. Positive hybridoma supernatants were identified after washing and detection of bound antigen by appropriate means.
