Fluorescent confocal image of U251 cell stained with IPF Antibody (C-term).U251 cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.1%, 10 min), then incubated with IPF 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.). Nuclei were counterstained with DAPI (blue) (10 ug/ml, 10 min). IPF immunoreactivity is localized to Cytoplasm and Nucleus significantly.
