Functional Studies - DNQX disodium salt, AMPA / kainate antagonist (ab120169)ab96379 staining MEK1 (phospho S298) in SK-N-SH cells treated with DNQX disodium salt (ab120169), by ICC/IF. Decrease in MEK1 (phospho S298) expression correlates with increased concentration of DNQX disodium salt, as described in literature.
The cells were incubated at 37°C for 3h in media containing different concentrations of ab120169 (DNQX disodium salt) 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 ab96379 (1/100 dilution) 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.
