THE ANAMNESTIC ANTIBODY RESPONSE TO TYPE III SPECIFIC PNEUMOCOCCAL POLYSACCHARIDE

Abstract
Rabbits immunized with killed type III pneumococci respond to anamnestic challenge by type specific polysaccharide (S III) with the synthesis of anti-S III antibody if a long interval is allowed to elapse between primary and secondary immunization. A study of the anti-S III antibody produced early and late in the immune response revealed no change in molecular class, banding pattern of dissociated light chains, or S III binding characteristics as measured under equilibrium conditions or by study of dissociation kinetics utilizing radioiodinated p-OH-benzyl-S III.
