Murine in vivo carrier-specific IgG memory to DNP-Ficoll: variation among inbred strains.

BALB/cAnN and C3H/HeN mice were primed and challenged with DNP-Ficoll, a thymic independent (TI-2) antigen. They developed significant carrier-specific IgG memory responses: DNP-pneumococcal polysaccharide or DNP-hemocyanin challenge did not elicit memory responses. NZB/B1NJ mice failed to develop this memory response. Genetically controlled events apparently regulate the phenotypic expression of this effect.
