生物活性

Luspatercept (ACE-536) is a recombinant modified ActRIIB fusion protein that binds with transforming growth factor β superfamily ligands. Luspatercept increases the erythrocyte numbers and promotes maturation of erythroid precursors. Luspatercept binds with GDF11 and inhibits Smad2/3 signaling. Luspatercept can be used for the research of anemia[1].

体外研究
(In Vitro)

Luspatercept (0.1-1000 ng/mL) 抑制 A204 细胞中 GDF11 和 GDF8 诱导的 Smad2 和 Smad 3 信号通路[1]
Luspatcept 与 GDF11,GDF8,activin B,BMP10 和 BMP6 结合[1]

体内研究
(In Vivo)

Luspatercept (0.1-60mg /kg,皮下注射;10mg /kg,静脉注射;每周 2 次,共 8 周) 增加小鼠、大鼠和猴子的红细胞 (RBC) 数量、血红蛋白水平和红细胞堆积[1]
Luspatercept (10mg /kg,皮下注射,1 次) 降低 C57BL/6 小鼠骨髓和脾脏中的红细胞形成单位 (BFU-Es) 和红血球形成单位 (CFU-Es)[1]
Luspatercept (10mg /kg,腹腔注射,1 次) 抑制小鼠脾脏 Smad2/3 磷酸化[1]

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.
