title: Elucidation of the antigenic determinant in lipotropin for two monoclonal antibodies.
abstract: Two monoclonal antibodies were found to give enhanced affinity for beta-lipotropin when mixed, as evidenced by competitive radioimmunoassay. Both monoclonals were found to react with a pentapeptide Ala-Glu-Leu-Glu-Tyr, which is a sequence of high local hydrophilicity within the N-terminal section of beta-lipotropin.
