All lanes : Anti-PTEN antibody [EPR9941] (ab154812) at 1/10000 dilution

Lane 1 : Wild-type HeLa cell lysate
Lane 2 : PTEN knockout HeLa cell lysate

Lysates/proteins at 20 µg per lane.

Performed under reducing conditions.

Predicted band size: 47 kDa
Observed band size: 47 kDa

Lanes 1- 2: Merged signal (red and green). Green - ab154812  observed at 47 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

ab154812 was shown to react with PTEN in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab255419 (knockout cell lysate ab263829) was used. Wild-type HeLa and PTEN knockout HeLa cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab154812  and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 10000 dilution and a 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 20000 dilution for 1 hour at room temperature before imaging.

Lanes 1- 2: Merged signal (red and green). Green - ab133532 observed at 47 kDa. Red - Anti-Vinculin antibody [VIN-54] observed at 124 kDa.

 ab133532 was shown to react with PTEN in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab255419 (knockout cell lysate ab263829) was used.

Lane 1 : Wild-type HeLa cell lysate
Lane 2 : PTEN knockout HeLa cell lysate
Lane 3 : HAP1 cell lysate

Observed band size: 47 kDa

Lanes 1 - 3: Merged signal (red and green). Green - ab133532 observed at 47 kDa. Red - loading control, ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37 kDa.

ab133532 was shown to react with PTEN in wild-type HeLa cells in western blot. The bands observed in PTEN knockout cell line ab255419 (PTEN knockout cell lysate ab263829) below 47 kDa may represent truncated forms and cleaved fragments. This has not been investigated further. HeLa wild-type and PTEN knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3 % milk in TBS-T (0.1 % Tween^®) before incubation with ab133532 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4 °C at a 1 in 10000 dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 h at room temperature before imaging.
