  Western blot - Anti-TDP43 antibody [EPR5811] (ab133547)

  ab133547 was shown to react with TARDBP in wild-type HAP1 cells in Western blot with loss of signal observed in a TARDBP knockout cell line. Wild-type HAP1 and TARDBP knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab133547 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with secondary antibodies at 0.2 µg/mL before imaging.

  Immunocytochemistry/ Immunofluorescence - Anti-TDP43 antibody [EPR5811] (ab133547)

  ab133547 was shown to react with TARDBP in wild-type HAP1 cells in immunocytochemistry with loss of signal observed in a TARDBP 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 ab133547 at 1/1000 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 ?g/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).
