重组Anti-ATG7抗体[EP1759Y] (ab52472)

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: ATG7 knockout HAP1 cell lysate (20 µg)
Lane 3: Jurkat cell lysate (20 µg)
Lane 4: HepG2 cell lysate (20 µg)

Lanes 1 - 4: Merged signal (red and green). Green - ab52472 observed at 77 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab52472 was shown to specifically react with ATG7 when ATG7 knockout samples were used. Wild-type and ProteinX knockout samples were subjected to SDS-PAGE. ab52472 and ab8245 (loading control to Apg7) were both diluted 1/2000 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.

Immunohistochemical analysis of paraffin-embedded human cervical carcinoma sections labelling ATG7 with purified ab52472 at a dilution of 1/500. The secondary antibody used was ab97051, Goat Anti-Rabbit IgG H&L (HRP) at a dilution of 1/500. The sample was counterstained with hematoxylin. Antigen retrieval was performed using EDTA Buffer; pH 9.0. PBS was used instead of the primary antibody as the negative control and is shown in the inset.

Immunocytochemistry/Immunofluorescence analysis of HeLa cells labelling ATG7 with purified ab52472 at 1/100. Cells were fixed with 4% Paraformaldehyde and permeabilised with 0.1% Triton X-100. ab150077, Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. Cells were counter-stained with ab7291 anti-Tubulin (mouse mAb) followed by ab150120, AlexaFluor^®594 goat anti-mouse secondary both at 1/1000. Nuclei were counterstained with DAPI (blue).

For negative control 1, rabbit primary antibody was used followed by anti-mouse secondary antibody (ab150120). For negative control 2, ab7291 (mouse primary antibody) was used followed by anti-rabbit secondary antibody (ab150077).

Flow cytometry analysis of HeLa cells labelling ATG7 (red) with purified ab52472 at dilution of 1/100. The secondary antibody used was goat anti rabbit IgG (FITC) at 1/500. Cells were fixed with 4% paraformaldehyde. Isotype control antibody was Rabbit monoclonal IgG (black). The blue line shows cells without incubation with primary antibody and secondary antibody.

ab52472 at 1/30 dilution immunoprecipitating ATG7 in HEK293 whole cell lysate observed at 70 KDa (lanes 1 and 2).

Lane 1 (input): HEK293 whole cell lysate 10ug

Lane 2 (+): ab52472 + HEK293 whole cell lysate

Lane 3 (-): Rabbit monoclonal IgG (ab172730) instead of ab52472 in HEK293 whole cell lysate

For western blotting, ab52472 was used followed by VeriBlot for IP Detection Reagent (HRP) (ab131366) for detection at a dilution of 1/10,000.

Blocking and Diluting buffer and concentration: 5% NFDM/TBST.

Immunocytochemistry/Immunofluorescence analysis of HT-29 (human colorectal adenocarcinoma) cells labelling ATG7 with purified ab52472 at 1/500. Cells were fixed with 100% methanol. An Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (ab150077) at 1/1000 dilution was used as the secondary antibody. Nuclei couterstained with DAPI (blue). 

Secondary Only Control: PBS was used instead of the primary antibody as the negative control. 

Overlay histogram showing HEK293 cells stained with unpurified ab52472 (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 (ab52472, 1/50 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight^® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 100% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
