staining ApoA1 in HepG1 cells treated with nicotinic acid (ab120145), by ICC/IF. Decrease in ApoA1 expression correlates with increased concentration of nicotinic acid, as described in literature.
The cells were incubated at 37°C for 72h in media containing different concentrations of ab120145 (nicotinic acid) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab64308
(5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899
) at 1/250 dilution was used as the secondary antibody.
