Recombinant Anti-Peroxiredoxin 2/PRP antibody [EPR5154] (ab109367)

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: Peroxiredoxin 2/PRP knockout HAP1 cell lysate (20 µg)
Lane 3: HeLa cell lysate (20 µg)
Lane 4: LnCaP cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab109367 observed at 24 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab109367 was shown to specifically react with Peroxiredoxin 2/PRP when Peroxiredoxin 2/PRP knockout samples were used. Wild-type and Peroxiredoxin 2 knockout samples were subjected to SDS-PAGE. ab109367 and ab8245 (loading control to GAPDH) were both diluted 1/1000 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 1/10 000 dilution for 1 h at room temperature before imaging.

Immunofluorescence staining of HeLa cells with purified ab109367 at a working dilution of 1/100, counter-stained with DAPI. The secondary antibody was Alexa Fluor^® 488 goat anti-rabbit (ab150077), used at a dilution of 1/1000. ab7291, a mouse anti-tubulin antibody (1/1000), was used to stain tubulin along with ab150120 (Alexa Fluor^® 594 goat anti-mouse, 1/1000), shown in the top right hand panel. The cells were fixed in 100% methanol and permeabilized using 0.1% Triton X 100. The negative controls are shown in bottom middle and right hand panels - for negative control 1, purified ab109367 was used at a dilution of 1/500 followed by an Alexa Fluor^® 594 goat anti-mouse antibody (ab150120) at a dilution of 1/500. For negative control 2, ab7291 (mouse anti-tubulin) was used at a dilution of 1/500 followed by an Alexa Fluor^® 488 goat anti-rabbit antibody (ab150077) at a dilution of 1/400.

Lanes 1- 2: Merged signal (red and green). Green - ab109367 observed at 22 kDa. Red - Anti-GAPDH antibody [6C5] - Loading Control (ab8245) observed at 37 kDa.

 ab109367 was shown to react with Peroxiredoxin 2/PRP in wild-type HEK-293T cells in western blot. Loss of signal was observed when knockout cell line ab266392 (knockout cell lysate ab257041) was used. Wild-type HEK-293T and PRDX2 knockout HEK-293T cell lysates were subjected to SDS-PAGE. Membrane was blocked for 1 hour at room temperature in 0.1% TBST with 3% non-fat dried milk. ab109367 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) overnight at 4°C at a 1 in 1000 dilution and a 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.

Overlay histogram showing HeLa cells fixed in 80% methanol and stained with purified ab109367 at a dilution of 1/200 (red line). The secondary antibody used was Alexa Fluorr^® 488 goat anti-rabbit at a dilution of 1/500. Rabbit monoclonal IgG was used as an isotype control (black line) and cells incubated in the absence of both primary and secondary antibody were used as a negative control (blue line). 

Overlay histogram showing HeLa cells stained with unpurifiedab109367 (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 (ab109367, 1/1000 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) (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.
