Immunoprecipitation - Anti-Tuberin antibody [EPR22886-235] - BSA and Azide free (AB256472)

Tuberin was immunoprecipitated from 0.35 mg HeLa (human cervix adenocarcinoma epithelial cell) whole cell lysate 10μg with ab255612 at 1/30 dilution (2μg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab255612. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/5000 dilution.

Lane 1 : HeLa (human cervix adenocarcinoma epithelial cell) whole cell lysate 10μg

Lane 2 : ab255612 IP in HeLa whole cell lysate

Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab255612 in HeLa whole cell lysate.

Blocking and dilution buffer and concentration : 5% NFDM/TBST.

Exposure time : 3 minutes.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab255612).

Western blot - Anti-Tuberin antibody [EPR22886-235] - BSA and Azide free (AB256472)

Western blot : Anti-TSC2 antibody [EPR22886-235] (ab255612) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab255612 was shown to bind specifically to TSC2. A band was observed at 200 kDa in wild-type A549 cell lysates with no signal observed at this size in TSC2 knockout cell line. To generate this image, wild-type and TSC2 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. 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 IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Western blot - Anti-Tuberin antibody [EPR22886-235] - BSA and Azide free (AB256472)

The molecular weight observed is consistent with what has been described in the literature (PMID : 30774414; 10335945).

ab255612 was shown to specifically react with Tuberin in wild-type HAP1 cells as signal was lost in Tuberin knockout cells. Wild-type and Tuberin knockout samples were subjected to SDS-PAGE. ab255612 and ab129002 (Recombinant Anti-Vinculin antibody [EPR8185]) 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 1/20,000 dilution for 1 hour at room temperature before imaging. The blot was developed on a BIO-RAD^® ChemiDoc^™ MP instrument using the ECL technique.

Blocking and dilution buffer : 5% NFDM/TBST.
