IgD ELISA kits are assays designed to detect immunoglobulin D (IgD), a class of antibody. IgD is a multi-subunit complex that contains two heavy chains and two light chains. It circulates in small amounts in the blood and is also present on the surface of human and murine B-lymphocytes, acting as a B cell antigen receptor. IgD ELISA kits can be useful for studies in B cell biology, and the innate and adaptive immune responses.
