Anti-HSP A5 Antibody

Produced in rabbit hosts and affinity-purified, this polyclonal primary antibody recognizes HSPA5, the 78 kDa endoplasmic reticulum chaperone also referenced as BiP and GRP78. The unconjugated reagent from Antibodies.com is validated across western blot, immunohistochemistry on paraffin and frozen sections, immunofluorescence microscopy, and ELISA workflows, detecting the endogenous stress-inducible protein in human, mouse, rat, and monkey samples. Each 100 µl vial supports studies of unfolded protein response activation, ER stress signaling, and chaperone-mediated protein folding, and is supplied for research use only as a flexible reagent for both cell-based imaging and tissue-level analysis.
