Immunocytochemistry/ Immunofluorescence - Anti-PARK7/DJ1 antibody [EPR19466-105] - BSA and Azide free (AB224529)

This data was developed using ab201147, the same antibody clone in a different buffer formulation.

ab201147 was shown to react with PARK7 in wild-type HEK-293T cells in immunocytochemistry with loss of signal observed in PARK7 knockout cell line ab266338. Wild-type and knockout cells were mixed and pelleted at a 1 : 1 ratio on coverslips. The cells were fixed with 4% paraformaldehyde (15 min) then permeabilized with 0.1% Triton X-100 (10min) and then blocked with 1x PBS, 0.01% Triton X-100, 5% BSA, 5% NGS. The cells were then incubated with ab201147 at 1/500 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat anti-rabbit secondary antibody to (Alexa Fluor® 555) at 0.5 µg/ml. Acquisition of the green (wild-type), red (antibody staining) and far-red (knockout) channels was performed. Representative grayscale images of the red channel are shown. Wild-type and knockout cells are outlined with yellow and magenta dashed line, respectively. Schematic representation of the mosaic strategy used is shown on the bottom-right panel. Image was acquired with a Zeiss(LSM-880).

Abcam and YCharOS are working together to help address the reproducibility crisis by enabling the life science community to better evaluate commercially available antibodies.

Immunofluorescent analysis of 100% methanol fixed LNCaP (Human prostate cancer cell line) cells labeling PARK7/DJ1 with ab201147 at 1/100 dilution, followed by  AlexaFluo^r®488 Goat Anti-Rabbit (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic and weak nuclear staining on LNCaP cells.

The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor^® 594)(ab195889) at 1/200 dilution (red).

Secondary antibody only control : Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab201147).

Intracellular flow cytometric analysis of 4% paraformaldehyde fixed HeLa (human cervix adenocarcinoma) cell line labeling PARK7/DJ1 with ab201147 at 1/120 (red) compared with a Rabbit monoclonal IgG (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077), at 1/2000 dilution was used as the secondary antibody.

Immunoprecipitation - Anti-PARK7/DJ1 antibody [EPR19466-105] - BSA and Azide free (AB224529)

PARK7/DJ1 was immunoprecipitated from 0.35 mg HEK-293T (human embryonic kidney) whole cell lysate with ab201147 at 1/60 dilution. Western blot was performed from the immunoprecipitate using ab201147 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.
Lane 1 : HEK-293T (human embryonic kidney) whole cell lysate 10 μg (Input).
Lane 2 : HEK-293T whole cell lysate.
Lane 3 : Rabbit monoclonal IgG (ab172730) instead of ab201147 in HEK-293T whole cell lysate.
Blocking and dilution buffer and concentration : 5% NFDM/TBST.
Exposure time : 3 seconds.

Western blot - Anti-PARK7/DJ1 antibody [EPR19466-105] - BSA and Azide free (AB224529)

This data was developed using ab182561, the same antibody clone in a different buffer formulation.

ab201147 was shown to react with PARK7 in wild-type HEK-293T cells in Western blot with loss of signal observed in PARK7 knockout cell line ab266338. Wild-type HEK-293T and PARK7 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab201147 overnight at 4 °C at a 1/5000 dilution. Blots were incubated with secondary antibodies at 0.2 µg/mL before imaging.
