title: [Hybridoma cultures using porcine serum not containing immunoglobulin and dialysis fractions].
abstract: The whole swine serum was treated with ammonium sulphate to precipitate immunoglobulins. The remained IgG was removed with the use of protein A-sepharose. The hybridoma cells producing monoclonal antibodies to lambda phage (class IgG) were cultured in Dalbecco's modified Eagle medium with addition of a 5% whole swine serum or of a treated unwhole one (final concentration of the protein being 3 mg/ml). Upon these conditions, hybridoma cells had similar growth rate and population density (1-1.3 X 10(6) cells/ml). Maximal antibody concentration was almost similar (80-90 mcg/ml). Purity of a sample of monoclonal antibodies isolated by the method of chromatography with the use of protein A-sepharose from supernatant containing the unwhole serum was no less than 99%, whereas it was considerably lower (12-15%) in the case of the whole serum.
