ab238126 Anti-GRP94 antibody [EPR22847-50] was shown to specifically react with GRP94 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266313 (knockout cell lysate ab257254) was used. Wild-type and GRP94 knockout samples were subjected to SDS-PAGE. ab238126 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.

GRP94 was immunoprecipitated from 0.35 mg of HeLa (human epithelial cell line from cervix adenocarcinoma) whole cell lysate with ab238126 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab238126 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used at 1/5000 dilution.

Lane 1: HeLa whole cell lysate 10 μg (Input).
Lane 2: ab238126 IP in HeLa whole cell lysate.
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab238126 in HeLa whole cell lysate.

Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 3 seconds.

Intracellular flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol-permeabilized HeLa (human epithelial cell line from cervix adenocarcinoma) cells labeling GRP94 with ab238126 at 1/600 dilution (red) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). 

Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077), at 1/2000 dilution was used as the secondary antibody.
