Immunofluorescence of Hela cells labelling Brachyury/Bry with ab156611. Hela cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with ab156611 (1/25, 1 h at 37°C). An Alexa Fluor® 488 conjugated donkey anti-rabbit antibody (green) was used as the secondary antibody (1/400, 50 min at 37°C). Cytoplasmic actin was counterstained with Alexa Fluor® 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37°C) and nuclei were counterstained with DAPI (blue) (10 µg/ml, 10 min). Brachyury/Bry immunoreactivity is localized to the nucleus.
