Western blot - Anti-PERK antibody [EPR19876-294] - BSA and Azide free (AB254249)

Blocking/Dilution buffer : 5% NFDM/TBST.

ab229912 was shown to specifically react with PERK in wild-type HAP1 cells as signal was lost in PERK knockout cells. Wild-type and PERK knockout samples were subjected to SDS-PAGE. ab229912 and ab181602 (Rabbit anti-GAPDH loading control) were incubated 1 hour at room temperature at 1/1000 dilution and 1/200,000 dilution respectively. Blots were developed with Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated (ab97051) secondary antibody at 1/100,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD® ChemiDoc™ MP instrument using the ECL technique.

This antibody also recognizes unidentifiable proteins below 75 kDa.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab229912).

This data was developed using ab229912, the same antibody clone in a different buffer formulation.

Western blot : Rabbit Monoclonal[11445] to KIFC1 ab172620 staining at 1/50000 dilution, shown in green; Mouse anti GAPDH (ab8245) loading control staining at 1/20,000 dilution, shown in magenta. A band was observed at 75 kDa in Wild-type A549 cell lysates with no signal observed at this size in KIFC1 knockout A549 cell line. To generate this image, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3pc Milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit 800CW & Goat anti-Mouse 680RD at 1/20,000 dilution.

To generate this image, wild-type and EIF2AK3 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C.
