Abstract
An agar gel radial diffusion technique has been devised to examine the amount of IgG and relative amounts of As 4 and As 5 in the sera of twenty heterozygous As/4,5 rabbits immunized with Type III pneumococci. Serial absorption of the sera with the polysaccharide SSS III antigen before reaction with anti-IgG and anti-allotypic sera was used to show how much specific IgG antibody was present in each serum and the distribution of this antibody between molecules bearing one or other or neither of the allotypic determinants.
