Anti-HLA-DRA Antibody

Offered by Antibodies.com as a research-grade primary antibody, this rabbit polyclonal reagent targets HLA-DRA (HLA class II histocompatibility antigen, DR alpha chain) and is supplied at the 50 µL size. The antibody was raised against a recombinant human HLA-DRA immunogen and affinity-purified, and it specifically detects endogenous levels of total HLA-DRA protein. It is unconjugated and formulated at 1.0 mg/mL in phosphate-buffered saline (pH 7.4) containing 150 mM sodium chloride, 0.02% sodium azide, and 50% glycerol, with magnesium and calcium omitted from the buffer. The host species is rabbit, clonality is polyclonal, and the reagent is intended for Western blot (WB) and immunohistochemistry (IHC) workflows. Validated reactivity spans human, mouse, and rat samples, making it a broadly useful tool across commonly studied model systems and primary human tissues. Shipping is performed at refrigeration temperature (4 °C); upon arrival the vial should be aliquoted and stored at –20 °C, with repeated freeze/thaw cycles avoided to preserve activity. For laboratory research use only, this reagent supports reproducible detection of HLA-DRA in cell lysates and tissue sections for immunology, transplantation, and antigen-presentation studies.
