Quantitative Studies on the Precipitin Reaction

Quantitative Studies on the Precipitin Reaction Effect of Salts on the P~eaction*

In the studies on the precipitin reaction hitherto published from this laboratory (1) the salt concentration was held constant at 0.9 per cent of sodium chloride in order to permit observations on the effect of varying the proportions of antigen (or hapten) and antibody. In the present paper are reported data obtained during several years on the influence on the course of the precipitin reactio...

Equine Antiserum Precipitin Reaction with VII. The Quantitative on Tobacco Mosaic Virus: Immunochemical Studies

Studies on Photo-oxidation of Antigen and Antibodies

1. Quantitative precipitin studies indicate that progressive photo-oxidation progressively destroys the antigenic function of egg albumin. 2. Quantitative precipitin reactions of antisera (anti-egg albumin rabbit serum and antipneumococcus Type I horse serum) demonstrate that progressive photo-oxidation causes progressive lowering of the potency of the sera. 3. Quantitative precipitin reactions...

Quantitative Studies on the Neutralization Reaction between African Horse-sickness Virus and Antiserum

A Quantitative Study of the Cross Reaction of Types Iii and Viii Pneumococci in Horse and Rabbit Antisera

1. A preparation of the specific polysaccharide of Type VIII pneumococcus is described in which the use of heat, strong acid, and alkali were avoided. 2. Quantitative estimations are given of the homologous and cross reacting precipitin and agglutinin in Types III and VIII antisera produced in the rabbit and in the horse. Quantitative data are also given on the mechanism of the Type VIII precip...
