title: The hydrolysis of human IgG with subtilisin.
abstract: Small amounts of subtilisin (0.1 mg. per ml.) in the absence of cysteine will instantaneously hydrolyze "enzyme-sensitive" IgG globulins. This procedure permits the identification of antibodies in whole serum and myeloma globulins in the ultracentrifuge with simplicity and speed unmatched by other technics.
