    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.

    This data was developed using the same antibody clone in a different buffer formulation (ab200837).

    Lanes 1-3: Merged signal (red and green). Green - ab200837 observed at 65 kDa. Red - loading control ab8245 observed at 36 kDa.

    ab200837 Anti-CstF-64 antibody [EPR15698] was shown to specifically react with CstF-64 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265207 (knockout cell lysate ab257402) was used. Wild-type and CstF-64 knockout samples were subjected to SDS-PAGE. ab200837 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 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.
