生物活性

TAT-CIRP is a a small peptide, refers to Trans-trans-activating (Tat)-cold-inducible RNA binding protein. TAT-CIRP is an inhibitor of myeloid differentiation protein 2 (MD2). TAT-CIRP exhibits robust neuroprotection against ischemic and hemorrhagic stroke in mice[1].

体内研究
(In Vivo)

TAT-CIRP (5-20mg/kg) 减轻大脑中动脉 (MCA) 闭塞 (MCAO) 小鼠缺血性中风后的脑损伤。至于 Tat,人类免疫缺陷病毒 1 型的细胞膜转导结构域,可用作对照肽[1]
TAT-CIRP (20 mg/kg;静脉注射;单剂量) 在小鼠中可通过血脑屏障,Cmax 值为 4762.6 μg/L,半衰期约为 90 分钟[1]
TAT-CIRP (20 mg/kg、100 mg/kg;静脉注射;每天一次,持续 7 天) 对小鼠几乎没有毒性,具有安全性[1]
TAT-CIRP 减少恒河猴的脑缺血损伤[1]

Animal Model: Middle cerebral artery (MCA) occlusion (MCAO) model in mouse[1]
Dosage: 5 mg/kg, 10 mg/kg, 20 mg/kg
Administration: IV; single dose or once daily for 7 days
Result: Resulted better neurological function at 28 days after brain hemorrhage than the mice that received saline.
Did not induce elevation of any liver transaminases or biomarkers of renal dysfunction.

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.
