Analysis by electrophoretic transfer blotting of Japanese cedar pollen allergens which react with IgG and IgE antibodies in the serum of patients.

Abstract

Crude extract of Japanese cedar pollen was fractionated by DEAE-cellulose chromatography to separate the major allergenic components. In order to analyze which antigens react with IgG or IgE antibodies in the serum of Japanese cedar pollinosis patients, an electrophoretic transfer blotting was performed. Both IgE and IgG antibodies reacted with several common antigens, while IgG additionally reacted with some low-molecular-weight proteins.
