    Lysates/proteins at 20 µg per lane.

    Performed under reducing conditions.

    Predicted band size: 57 kDa
    Observed band size: 57 kDa



    This data was developed using the same antibody clone in a different buffer formulation (ab134950).

      Lanes 1- 2: Merged signal (red and green). Green - ab134950 observed at 57 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

     ab134950 was shown to react with PTBP1 in wild-type HeLa cells in western blot. Loss of signal was observed when knockout cell line ab265155 (knockout cell lysate ab257614) was used. Wild-type HeLa and PTBP1 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. ab134950 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 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.

    This data was developed using the same antibody clone in a different buffer formulation (ab134950).

    Lanes 1 - 2: Merged signal (red and green). Green - ab134950 observed at 57 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab134950 was shown to specifically react with PTBP1 in wild-type HAP1 cells as signal was lost in PTBP1 knockout cells. Wild-type and PTBP1 knockout samples were subjected to SDS-PAGE. ab134950 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed 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 1/10000 dilution for 1 hour at room temperature before imaging.
