Description

(Arg)9 (Nona-L-arginine) acetate is a cell-penetrating peptide (CPP) made up of 9 arginine residues. (Arg)9 acetate has neuroprotective property, exhibits neuroprotective activity with an IC50 of 0.78 μM in the glutamic acid model[1][2].

IC50 & Target

IC50: 0.78 μM (neuroprotection)[1]

In Vitro

(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].

In Vivo

(Arg)9 (Nona-L-arginine; 1 μM/kg (600  μL); i.v.; once, for 30min; male Sprague–Dawley ratspermanent middle cerebral artery stroke model) acetate shows neuroprotective effects and reduces infarct volume[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
