A sensitive immunoassay was used to identify recombinant DNA plasmids carrying cDNA fragments of bovine caseins in the cDNA library from rRNA of bovine mammary glands. Colonies grown on nitrocellulose filters were lysed in situ and proteins from the lysates were blotted onto CNBr-activated filter paper. Antigens covalently bound to the CNBr-activated paper or bound to the nitrocellulose filters were detected by reaction with antiserum to caseins, followed by 125I-labeled protein A from Staphylococcus aureus and autoradiography. Four clones were positive among 5400 bacterial clones of the cDNA library--al, b2, b5, h7. Molecular weights of chimeric proteins pre-beta-lactamase:casein synthesized in Escherichia coli were determined by immunoblotting. Colony hybridization and DNA sequence analysis showed that clone b5 contained cDNA fragment of bovine kappa-caseins and clone h7 cDNA fragment of beta-casein. The last clone was designated pKcas beta-7.
