Chemical name(RS)-α-Amino-3-hydroxy-5-methylisoxazole-4-propionic acid
Storage instructionsStore at Room Temperature. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 10 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

ab96379 staining MEK1 (phospho S298) in SK-N-SH cells treated with (R,S)-AMPA (ab120130), by ICC/IF. Increase in MEK1 (phospho S298) expression correlates with increased concentration of(R,S)-AMPA, as described in literature.
The cells were incubated at 37°C for 24h in media containing different concentrations of ab120130 ((R,S)-AMPA) 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.
