Description

HSPA5 (heat shock 70kDa protein 5) also known as glucose-regulated protein, 78kD(GRP78) or BiP, is a member of the heat-shock protein-70 (HSP70) family and is involved in the folding and assembly of proteins in the endoplasmic reticulum.BiP is an essential component of the translocation machinery, as well as playing a role in retrograde transport across the ER membrane of aberrant proteins destined for degradation by theproteasome. Shen et al.(2002)concluded thatBiPretains ATF6 in the ER by inhibiting its Golgi localization signals and that dissociation ofBiPduring ER stress allows ATF6 to be transported to the Golgi. The findings ofShen et al.(2002)demonstrated thatthe proteinis a key element in sensing the folding capacity within the ER.

Application Notes

The stated application concentrations are suggested starting points. Titration of the BiP antibody may be required due to differences in protocols and secondary/substrate sensitivity.

Immunogen

An amino acid sequence from the C-terminus of human GRP78/BiP (EWLESHQDADIEDFK) was used as the immunogen for this BiP antibody (100% homologous in human, mouse and rat).

Storage

After reconstitution, the BiP antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
