title: H-2 haplotype and sex-related differences in IgG response to ovalbumin in mice.
abstract: Specific IgG antibodies were determined by enzyme-linked immunosorbent assay (ELISA) in 7 strains of male and female mice after immunization with ovalbumin. Also, H-2 haplotype and sex-related differences in IgG response to ovalbumin were evaluated using statistical methods, slope ratio assay and parallel line assay. H-2k strain mice (C3H/HeN and CBA/JN) showed higher IgG responsiveness to ovalbumin than H-2d (BALB/cAnN and DBA/2 N) and H-2b (C57BL/6 N) mice. With regard to the sex-related differences in IgG response to ovalbumin, females in some strains showed higher IgG response than males, but some strains showed no sex-related differences, and sex-related differences in IgG response to ovalbumin did not relate to their H-2 haplotypes. These results may be caused by other immune response genes which control the sex-related immune response than H-2 or other unknown factors.
