    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

    Predicted band size: 61 kDa
    Observed band size: 65 kDa
    why is the actual band size different from the predicted?



    This data was developed using the same antibody clone in a different buffer formulation (ab223849).

      Lanes 1- 2: Merged signal (red and green). Green - ab223849 observed at 65 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

     ab223849 was shown to react with PAK1 in wild-type HeLa cells in western blot. The band observed in knockout cell line ab264889 (knockout cell lysate ab257572) lane below 65kDa may represent truncated forms and cleaved fragments. This has not been investigated further. Wild-type HeLa and PAK1 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. ab223849 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated 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.

    The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) (red) at 1/200 dilution.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

    PAK1 was immunoprecipitated from 0.35 mg SH-SY5Y (human neuroblastoma cell line from bone marrow) whole cell lysate with ab223849 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab223849 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: SH-SY5Y whole cell lysate 10 μg (Input).

    Lane 2: ab223849 IP in SH-SY5Y whole cell lysate.

    Lane 3: Rabbit monoclonal IgG (ab172730) instead of  ab223849 in SH-SY5Y whole cell lysate.

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

    Exposure time: 1 second.
