ab51037 used at a 1/200 dilution (red) to detect CD44 in human MDA-MB-231 cells by Flow Cytometry. The secondary used was a Pgoat anti-rabbit IgG (Alexa Fluor® 488) polyclonal used at a 1/2000 dilution. Isotype control (black): Rabbit monoclonal IgG (ab172730). Unlabelled control (Blue): Cell without incubation with primary antibody and secondary antibody.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab51037).

Performed under reducing conditions.
Predicted band size: 82 kDa
Observed band size: 80 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 (ab51037).
Lanes 1 - 4: Merged signal (red and green). Green - ab51037 observed at 80 kDa. Red - loading control, ab8245 (Mouse anti-GAPDH antibody [6C5]) observed at 37kDa.
ab51037 was shown to react with CD44 in wild-type HeLa cells in western blot. Loss of signal was observed when CD44 knockout sample was used. Wild-type HeLa and CD44 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 3% milk in TBS-T (0.1% Tween®) before incubation with ab51037 and ab8245 (Mouse anti-GAPDH antibody [6C5]) overnight at 4°C at a 1 in 5000 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 hour at room temperature before imaging.
