    This data was developed using ab254254, the same antibody clone in a different buffer formulation.

    Lanes 1-4: Merged signal (red and green). Green - ab254254 observed at 52,65 kDa. Red - loading control ab8245 observed at 36 kDa.

     ab254254 Anti-Heparanase 1 antibody [EPR22365-230] was shown to specifically react with Heparanase 1 in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265413 (knockout cell lysate ab258456) was used. Wild-type and Heparanase 1 knockout samples were subjected to SDS-PAGE. ab254254 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.
