Quantitative Studies on the Fixation Ratio "Complement: Antibody" in Complement-Fixation Tests with Syphilitic Serum

Abstract

Kaup and Kretschmer (1917) were the first to introduce a quantitative evaluation of syphilitic serum by adding varying amounts of complement (C') to a constant antigen-antibody mixture. Later, especially in the past decade, some important papers were published in which the respective relations between antibody, antigen and C' were studied in different ways (
