Abstract

Allotypes of membrane IgD of 27 strains of mice were determined with a series of anti-delta reagents, each capable of binding to the IgD of BALB/c spleen cells. One of these reagents is a newly defined allospecific rabbit anti-mouse-delta a. Typing with these reagents reveals the strain distribution of the previously described IgD.36 (Ig5.1) and IgD.43 (Ig5.4) specificities and demonstrates the existence of a new specificity, IgD.45 (Ig5.5). The results confirm the previous subdivision of the Igh-Ce haplotype into Igh-Ce, to which A mice are assigned, and Igh-Cn, to which NZB and NZW mice are assigned. In addition, it is shown that the Igh-Cd haplotype must also be subdivided. AKR mice, which express the a allele at the Igh-5(delta) locus, are designated as possessing the Igh-Cd haplotype while AL/N and C.AL20 mice, which have the e allele at the Igh-5(delta) locus, are assigned a new Igh-C haplotype designation, o.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
