Anti-Human Immunoglobulin D (IgD) Antibody

Affinity purified from goat host cells, this unconjugated polyclonal primary antibody selectively binds human Immunoglobulin D, supporting clear detection of soluble and membrane-bound IgD isoforms in immunological research. Validated applications include ELISA for quantifying IgD in cell culture supernatants and isolated samples, alongside flow cytometry (FC) to discriminate IgD-positive from IgD-negative B-cell subsets within peripheral blood mononuclear cells and lymphoid tissue preparations. The product is supplied as a 1 mg liquid aliquot in a vial, free of carrier protein, which lets researchers conjugate fluorophores, biotin, or enzymes as needed for their assay design. For day-to-day use, refrigerate the vial; for long-term retention, aliquot and store frozen, limiting freeze-thaw cycles to preserve binding affinity. Manufactured by Antibodies.com for research use only, this reagent is intended for in vitro studies of human B-cell maturation, class-switch recombination, and IgD-associated signaling pathways.
