Description

Application

Anti-GRP78/BiP (ET-21) antibody produced in rabbit is suitable for use as a primary antibody:
• for immunofluorescence staining of frozen heart tissue to examine whether ER stress signaling activation occurs in cardiomyocytes
• to detect Bip by immunoblotting of protein extract from WT AB strain of zebrafish (Danio rerio)
• at a working dilution of 1:1000 to detect GRP78 in extract of prostate cancer cells after androgen deprivation therapy
It is also suitable for immunoblotting at a working dilution of 1:3000 using human epitheloid carcinoma HeLa whole cell extract and for immunocytochemistry at a working dilution of 1:1000 using mouse fibroblasts NIH3T3 cells.

Physical form

Biochem/physiol Actions

The GRP78 (78-kDa glucose-regulated protein) is a member of the heat shock proteins Hsp70 required for cell viability. It is a Ca2+-binding molecular chaperone that is localized to the endoplasmic reticulum (ER). It plays a key role in proper glycosylation, folding and assembly of newly synthesized membrane bound or secretory proteins. It also facilitates retention of mutant or defective proteins that are improperly folded and prevents translocation of such proteins from the cytosol to the ER lumen. The protein is induced under conditions of stress such as oxidative stress, chemical toxicity, glycosylation and hypoxia. It plays a crucial role in the maintenance of cell homeostasis and the prevention of apoptosis and acts as a biomarker of hypoglycemia. It has a neuroprotective function in neurons exposed to glutamate exotoxicity and oxidative stress.
