Fluorescent confocal image of U251 cell stained with 042572. U251 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with 042572 (1:25, 1h at 37ºC). For secondary antibody, Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used (1:400, 50 min at 37ºC).Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37ºC). Nuclei were counterstained with DAPI (blue) (10ug/ml, 10 min). TADA3L immunoreactivity is localized to Nucleus significantly.
