Immune responses of inbred guinea pigs against random terpolymers containing L glutamic acid and L alanine. 1975

P H Maurer

The immune responses of the inbred guinea pig strains 2 and 13 have been determined against random terpolymers of L glutamic acid and L alanine and a third amino acid. Strain 2 guinea pigs responded against GAT10, GAT20(LLD), GAT10(NO2)15, GAT4, and GAL10. However, strain 13 guinea pigs responded only against GAT10. The explanation offered is that strain 2 guinea pigs, which have the Ir-GA gene, recognize the polymers via random GA determinants present in sufficient concentration in all of the above polymers. However, strain 13 guinea pigs recognize the GAT10 via the Ir-GT gene, and reduction in the concentration of tyrosyl residues below 10 mole % by various procedures alters the concentration of available random GT determinants necessary for interaction with the gene product of the Ir-GT gene.

D007104 Immune Adherence Reaction A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.
