Lane 1 (input): Human brain tissue lysate (10µg)
Lane 2 (+): ab76291+ human brain tissue lysate.
Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab76291 in human brain lysate
For western blotting, ab76291 at 1/1000 dilution (0.7 μg/mL) and VeriBlot for IP Detection Reagent (HRP) (ab131366) at 1/5000 were used.

The 30 kDa band is an intracellular fragment, and the 140 kDa observed MW which is higher than the predicted one is due to the glycosylation modification. (refer to ab189903).

Overlay histogram showing SH-SY5Y (human neuroblastoma cell line from bone marrow) cells stained with unpurified ab76291 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab76291, 1/50 dilution) for 30 min at 22°C. The secondary antibody used was DyLight^® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit monoclonal IgG (1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with methanol (5 min) used under the same conditions.Please note that Abcam do not have data for use of this antibody on non-fixed cells. We welcome any customer feedback.
