The IA6-2 monoclonal antibody reacts with the heavy chain of human Immunoglobulin D (IgD), a type I transmembrane glycoprotein and member of the immunoglobulin superfamily. IgD is co-expressed with membrane IgM on the surface of mature naïve B cells, where both isotypes associate with the Igα/Igβ (CD79a/CD79b) signaling heterodimer to form the B cell antigen receptor (BCR) complex. Engagement of the IgD-BCR by antigen mediates signal transduction that fine-tunes B cell activation, selection, and tolerance, complementing rather than duplicating IgM-BCR signaling. IgD expression is lost following isotype class switching, and a soluble form of IgD circulates at low levels in serum, where it has also been implicated in mucosal innate immune defense through interactions with basophils and mast cells.

RECOMMENDED USAGE

Flow cytometry: The suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL.
