Isolation and characterization of monoclonal antibody directed against bovine alpha s2-casein.

A monoclonal antibody 62-1A of isotype IgM, directed against bovine alpha s2-casein, was isolated and characterized. Monoclonal antibody 62-1A recognized bovine alpha s2-11P- and alpha s2-9P-caseins by indirect solid phase radioimmunoassay and Western blot analysis. Crossreactivity toward native genetic variants (A, B, and C) of alpha s1-casein was similar but lower (approximately 60 to 70%) than that for alpha s2-11P-casein). Little or no crossreactivity was observed for other bovine milk or serum proteins. Antibody affinity for alpha s2-11P-casein was 1.3 x 10(9)/M. As little as 25 ng/ml (.5 ng/well) of alpha s2-11P-casein was detected by solid phase radioimmunoassay.
