Fluorescent image of A549 cell stained with NPM1 Antibody (C-term)(Cat#AP2834b/SH090717BE).A549 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with NPM1 primary antibody (1:25, 1 h at 37?). For secondary antibody, Alexa Fluor� 488 conjugated donkey anti-rabbit antibody (green) was used (1:400, 50 min at 37?).Cytoplasmic actin was counterstained with Alexa Fluor� 555 (red) conjugated Phalloidin (7units/ml, 1 h at 37?).NPM1 immunoreactivity is localized to Nucleus and Nucleolus significantly.
