Biological Activity
IC50: 0.78 μM (neuroprotection)[1]
(Arg)9 (Nona-L-arginine; 5-10 μM) acetate provides significant neuroprotection in a dose–response manner following glutamic acid exposure (IC50=0.78 μM). Following kainic acid exposure, (Arg)9 acetate is neuroprotective, but less effective than in the glutamic acid model (IC50=0.81 μM). (Arg)9 acetate also shows neuroprotection following in vitro ischemia (IC50=6 μM)[1].

H2O : ≥ 50 mg/mL (33.70 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light, under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
