IgD is the major antigen receptor isotype coexpressed with IgM on the surface of most peripheral B cells.(Note: No cross-reactivity with haplotypes Igh-Cb or Igh-Ce has been observed for this antibody.) Hybridoma Production: SJL mice were immunized with spleen cells from BALB/c mice and the resultant SJL splenocytes were fused with SP2/0 cells. Recognition of IgD haplotype Igh-Ca was confirmed by FACS analysis. References: Stall, A. and M.
