Overlay histogram showing HepG2 cells stained with ab110265 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab110265, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HepG2 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
Western blot - COX6A1 antibody [14A3AD2BH4 ] (ab110265)
All lanes : Anti-COX6A1 antibody [14A3AD2BH4] (ab110265) at 5 µg/ml
Lane 1 : Human Heart Lysate Lane 2 : Rat Heart Lysate Lane 3 : Mouse Heart Lysate Lane 4 : HepG2 cell lysate
Predicted band size : 12 kDa Extra bands in the mouse sample (lane 3) are due to the reaction of the IgG-specific goat anti-mouse secondary antibody with residual mouse blood in the heart tissue, as it is very difficult to entirely remove the blood from these small organs.
