SpecificityThis antibody reacts with the delta chain of human IgD. Traces of contaminating antibodies have been removed by solid phase absorption. Only the IgD arch appeared in crossed immunoelectrophoresis.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/40 - 1/100. Perform enzymatic antigen retrieval before commencing with IHC staining protocol.
RelevanceLittle is known about the normal function of IgD, and few clinical signs or symptoms are associated with its absence. Individuals with low or absent levels of IgD do not appear unusually predisposed to infections. In mice, IgD may substitute for some functions of IgM when IgM is absent. IgD is expressed on peripheral B cells and is used as a pan B cell marker.
