title: The effects of PEG on second antibody immunoprecipitation and its use in immunoassay.
abstract: The effects of PEG on the second antibody immunoprecipitation have been studied in several radioimmunological systems. The following parameters have been studied in the assays: the average molecular weight and concentration of PEG, the species of the animal producing the first and second antibody, the nature of the antigen, the concentration of carrier immunoglobulins, and the rate of the immunoprecipitation. Thus, optimal conditions for the use of PEG with a second antibody have been defined in order to be used in any liquid phase immunoassay.
