Immunofluorescent analysis of steroidogenic acute regulatory protein isoform 1 showing staining in the mitochondria of HepG2 cells. HepG2 cells were fixed in 4% paraformaldehyde at RT for 15 min and stained using a steroidogenic acute regulatory protein isoform 1 polyclonal antibody (Product # PA5-21687) diluted at 1:500. Blue: Hoechst 33342 staining.
