title: A rapid assay for immunoglobulin in hybridoma supernatants.
abstract: A single step assay is described which allows detection of IgM and IgG in tissue culture supernatants at concentrations below 100 ng/ml. The assay is based on the agglutination of staphylococcal protein A coated sheep red blood cells (E-spA) in the presence of an enhancing antibody. The assay was designed for the rapid screening of antibody production by hybridoma cultures.
