Immunofluorescent analysis of ATF4 in human neuroblastoma cell line (SK-N-BE). Sample was fixed with 4% formaldehyde (15 min at RT), incubated with ATF4 monoclonal antibody (Product # MA5-27721) using a dilution of 1:100 (1 hour at RT), and followed by Goat Anti-Mouse 488, Phalloidin Texas Red and DAPI secondary antibody at a dilution of 1:100, 1:1000 (60 min at RT) and 1:5000 (5 min at RT). Images are shown as follows: (A) DAPI (blue) nuclear stain, B) Phalloidin Texas Red F-Actin stain, C) ATF4 Antibody, D) Merged image. Magnification: 60x.
