The Precipitin Reaction of Antipneumococcus Sera
The precipitin indices for a number of monovalent and polyvalent antipneumococcus sera were determined under known conditions, and found to vary as did the number of protective units. The ratio precipitin index/protective units in monovalent sera was found to lie between 2.8 and 4.8 for Type I and to be about ten times greater for Type III. Lower values were found in polyvalent horses and when ...
متن کاملSurface Tension of Sera as Affected by the Precipitin Reaction
An attempt to find evidence, through the study of surface tension, using the du Noüy tensiometer, of a denaturing effect of the precipitin reaction upon either the antigen or the immune serum yielded entirely negative results.
متن کاملSpecific Proteins of Antipneumococcus Sera Ii. Immunological Fractionation 01~ Type I Antipneumococcus Horse and Rabbit Sera
In the preceding paper of this series (1) it was reported that the amount of specific antibody precipitable by the capsular polysaccharide is related to the mouse protective value of Type I antipneumococcus serum only under certain well defined conditions. Thus with Type I antipneumococcus rabbit serum there was a direct proportionality between the two determined values. The protective ratio fo...
متن کاملProperties of the Type Specific Proteins of Antipneumococcus Sera
The generally held view has been that in any immune serum only a single antibody would be induced by and react with a single antigen. Were this true the various manifestations of antibody activity should show a quantitative parallelism. It has already been shown (1), however, that with antipneumococcus horse serum the mouse protective potency does not parallel the maximum amount of specifically...
متن کاملA Note on the Production of Antipneumococcus Sera
Horses immunized to Type I pneumococci developed serum, 0.1 cc. of which protected against 0.5 cc. of a virulent culture, 0.000001 cc. of which killed mice in less than 40 hours. Protective tests of serum from horses immunized to Type II organisms varied, 0.1 cc. protecting, however, in certain instances against 0.1 and 0.01 cc. of virulent homologous culture. Types I and II sera obtained in ou...
