Anti-P4HB antibody [RL90] (ab2792)

Western blot analysis of P4HB (PDIA1) was performed by loading 25 ug of HepG2 (Lane 1) Hela (Lane 2) and NIH-3T3 (Lane 3) cell lysates onto an SDS polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked at 4°C overnight. The membrane was probed with ab2792 at 1:1000 overnight at 4°C and washed in TBST. The membrane was then probed with a HRP-conjugated secondary antibody for 1 hr at room temperature in the dark. Chemiluminescent detection was performed using a ECL Plus Western Blotting Substrate. Results show a band at approx. 57 kDa.

Immunocytochemistry/Immunofluorescence analysis of P4HB (PDIA1) (red) in U2OS cells. Formalin fixed cells were permeabilized with 0.1% Triton X-100 in PBS for 10 minutes at room temperature and blocked with 2% BSA in PBS + 0.1% Triton X-100 for 30 minutes at room temperature. Cells were probed with ab2792 (1:75) for at least 1 hour at room temperature and incubated with DyLight 550 goat anti-mouse IgG secondary antibody (1:250) for 30 minutes at room temperature. Actin was stained with DyLight 488 Phalloidin at a dilution of 1:300 (1 unit/ml final concentration) for 30 minutes. Images were taken at 20X magnification.

Immunohistochemistry was performed on both normal and cancer biopsies of deparaffinized Human colon tissue tissues. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:200 with a mouse monoclonal antibody recognizing P4HB (PDIA1) ab2792 or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Overlay histogram showing HeLa cells stained with ab2792 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2792, 0.5µg/1x10⁶ cells) for 30 min at 22ºC. The secondary antibody used was DyLight^® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.
