Flow Cytometry (Intracellular) - Anti-GRP78 BiP antibody [EPR4041(2)] - BSA and Azide free (AB236050)
Intracellular Flow Cytometry analysis of HeLa (human cervix adenocarcinoma) cells labeling GRP78 BiP with purified ab108615 at 1/200 dilution (10ug/mL) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor®488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab108615).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-GRP78 BiP antibody [EPR4041(2)] - BSA and Azide free (AB236050)
Immunohistochemical staining of paraffin embedded human hepatocellular carcinoma with purified ab108615 at a working dilution of 1/500. The secondary antibody used is HRP goat anti-rabbit IgG H&L (ab97051) at 1/500. The sample is counter-stained with hematoxylin. Antigen retrieval was perfomed using Tris-EDTA buffer, pH 9.0. PBS was used instead of the primary antibody as the negative control, and is shown in the inset.

Biological function summary
GRP78/BiP is important in the unfolded protein response (UPR) a cellular stress response related to the ER. It is part of a complex that manages protein load inside the ER by regulating the fold of nascent proteins and interacting with other ER stress sensors like IRE1 PERK and ATF6. This function is essential for maintaining proper protein conformation in the ER especially during physiological stress ensuring that only correctly folded proteins proceed to the Golgi apparatus.
Pathways
GRP78/BiP significantly affects the UPR and apoptosis pathways. By controlling protein folding and quality in the ER GRP78 helps prevent cell death under stress conditions. It works closely with other proteins like ATF6 which activates stress response genes. In normal conditions GRP78 keeps stress transducers inactivated but during stress it dissociates allowing UPR signaling to occur.
