Recombinant Anti-TRAF2 antibody [EPR6048] (ab126758)

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: TRAF2 knockout HAP1 cell lysate (20 µg)
Lane 3: Human skeletal muscle lysate (20 µg)
Lane 4: U2OS cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab126758 observed at 55 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab126758 was shown to specifically react with TRAF2 when TRAF2 knockout samples were used. Wild-type and TRAF2 knockout samples were subjected to SDS-PAGE. ab126758 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. 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 1/10000 dilution for 1 h at room temperature before imaging.

Immunofluorescence staining of HeLa cells with purified ab126758 at a working dilution of 1 in 100, counter-stained with DAPI. Tubulin was stained with mouse anti-tubulin at a dilution of 1/1000 (ab7291) and Alexa Fluor^® 594 goat anti-mouse at a dilution of 1/500 (ab150120) . The secondary antibody was ab150077 Alexa Fluor^® 488 goat anti rabbit, used at a dilution of 1 in 500. The cells were fixed in 4% PFA and permeabilized using 0.1% Triton X 100. The negative controls are shown in the bottom middle and right hand panels - for the first negative control, purified ab126758 was used at a dilution of 1/200 followed by an Alexa Fluor^® 555 goat anti-mouse antibody at a dilution of 1/500 and for the second negative control mouse primary antibody (ab7291) and anti-rabbit secondary antibody (ab15007) were used.

Overlay histogram showing HeLa cells stained with unpurified ab126758 (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 (unpurified ab126758, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was Alexa Fluor® 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) (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.
