Anti-OTUB1 抗体 (ab101471)

Lanes 1-2: Merged signal (red and green). Green - ab101471 observed at 130 kDa. Red - loading control ab8245 observed at 37 kDa.

 ab101471 Anti-OTUB1 antibody was shown to specifically react with OTUB1 in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab266551 (knockout cell lysate ab257569) was used. Wild-type and OTUB1 knockout samples were subjected to SDS-PAGE. ab101471 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 10000 ug/ml 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 - ab101471 observed at 31 kDa. Red - loading control, ab18058, observed at 130 kDa.

ab101471 was shown to recognize OTUB1 in wild-type HAP1 cells as signal was lost at the expected MW in OTUB1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and OTUB1 knockout samples were subjected to SDS-PAGE. ab101471 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1µg/mL and 1/20000 dilution respectively. Blots were developed 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 1/20000 dilution for 1 hour at room temperature before imaging.

Secondary antibody - goat anti-rabbit HRP (ab97080)

ICC/IF image of ab101471 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab101471, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, goat anti-rabbit DyLight® 488 (IgG H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in 4% PFA fixed (10 min) Hek293, HepG2 and MCF7 cells at 5µg/ml, and in 100% methanol fixed (5 min)HeLa, HepG2 and MCF7 cells at 5µg/ml.
