Recombinant Anti-PGP9.5 antibody [EPR4118] - Neuronal Marker (ab108986)

Lanes 1 - 5: Merged signal (red and green). Green - ab108986 observed at 25 kDa. Red - loading control, ab8245 observed at 37 kDa.

ab108986 was shown to react with PGP9.5 in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab255443 (knockout cell lysate ab263773) was used. Wild-type and PGP9.5 knockout samples were subjected to SDS-PAGE. ab108986 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.

Lanes 1 - 4: Merged signal (red and green). Green - ab108986 observed at 24 kDa. Red - loading control, ab8245, observed at 37 kDa.

Ab108986 was shown to specifically react with UCHL1 in wild-type cells as signal was lost in UCHL1 knockout HAP1 cells.

A Goat anti rabbit IgG (Alexa Fluorr^® 488, ab150077) at 1/2000 dilution was used as the secondary antibody. 

PGP9.5 was immunoprecipitated from 0.35 mg Human fetal brain lysate  with ab108986 at 1/20 dilution (0.5μg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab108986 1/500 dilution (0.17 μg/ml). VeriBlot for IP Detection Reagent (HRP) (ab131366) was used as the secondary antibody at 1/1000 dilution.

Overlay histogram showing SH-SY5Y cells stained with ab108986 (red line). The cells were fixed with 4% paraformaldehyde (10 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 (ab108986, 1/10000 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluorr^® 488 goat anti-rabbit IgG (H&L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (0.1µg/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 SH-SY5Y cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
