Fig4: Flow cytometric analysis of Frizzled-5 was done on HepG2 cells. The cells were fixed, permeabilized and stained with Frizzled-5 antibody at 1/100 dilution (blue) compared with an unlabelled control (cells without incubation with primary antibody; red). After incubation of the primary antibody on room temperature for an hour, the cells was stained with a Alexa Fluor™ 488-conjugated goat anti-rabbit IgG Secondary antibody at 1/500 dilution.
