General description

Formalin-fixed and heat-killed Staphylococcus aureus cells bearing protein A that bind to the Fc portion of human IgG subclasses 1, 2, and 4, and to IgG from other species (binding capacity: ≥2 mg human IgG/100 mg cells). Used for many purposes, including radioimmunoassays, enzyme immunoassays, agglutination, and immunoprecipitation of antigens. PANSORBIN also stimulates B-lymphocyte production and inhibits neoplasm growth. Lyophilized from preparations of Cat. No. 507858. Note: size of 5 g or 1 g refers to the wet cell weight.
