The Purification of the Antibodies in Type I Anti-pneumococcus Serum, and the Chemical Nature of the Type-specific Precipitin Reaction

1. Methods for the concentration of Type I pneumococcus antibody have been outlined. 2. The physical and chemical properties of the purified antibody have been described. 3. The chemical basis of serological specificity has been discussed.

Agglutination by Precipitin

Serum (antigen) when heated at a temperature sufficient to cause definite clouding reacts more intensely with a specific precipitin than a portion of the unheated serum or samples heated at lower temperatures. The phenomenon is explained on the basis that coagulated protein in suspension is covered with undenatured antigen and the addition of precipitin causes agglutination of the coagulated pr...
