Immunocytochemistry/ Immunofluorescence - Anti-PARK7/DJ1 antibody [EP2815Y] - BSA and Azide free (AB218373)

This data was developed using ab76008, the same antibody clone in a different buffer formulation.

ab76008 was shown to react with PARK7 in wild-type HEK-293T cells in immunocytochemistry with loss of signal observed in a PARK7 knockout cell line. 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 ab76008 at 1/100 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).
