Anti-HSP90B Antibody

Raised in rabbit and supplied at 1 mg/ml in PBS with 0.1% sodium azide plus 50% glycerol, this Antibodies.com reagent targets HSP90B (also called GRP94, GP96, or endoplasmin), an endoplasmic reticulum-resident chaperone of the HSP90 family. Each 100 µl vial is validated for western blot, immunohistochemistry, and immunofluorescence workflows and shows reactivity with human, mouse, and rat samples, supporting comparative studies of ER stress, the unfolded protein response, immunoglobulin assembly, and tumor-associated immunogenic cell death where surface-exposed GRP94 acts as a damage-associated molecular pattern. For routine use, aliquot the glycerol-stabilized stock on arrival and store frozen to limit freeze-thaw cycles; the unconjugated format leaves open freedom to pair the reagent with a fluorophore- or HRP-labeled secondary of choice.
