研究方向
ACVR2A(基因位于 2q22.3)是TGF-β受体超家族成员。作为激活素(Activin)、骨形态发生蛋白(BMP)等配体的共同受体,通过SMAD依赖/非依赖通路调控胚胎发育、骨骼形成及组织修复,在纤维化疾病、癌症和代谢紊乱中发挥双重作用(促生长或促凋亡取决于配体微环境)。其突变与遗传性出血性毛细血管扩张症(HHT)和肌肉萎缩相关。
生物活性
Measured by its ability to inhibit Activin A-induced hemoglobin expression in K562 human chronic myelogenous leukemia cells. Approximately 0.01-0.05 μg/mL of Recombinant Human (rh) Activin RIIA Fc Chimera will inhibit 50% of the biological response due to 3 ng/mL of rhActivin A.

描述:
Recombinant Human Human ACVR2A Protein is produced by 293F expression system. The target protein is expressed with sequence (Ala20-Pro134) of Human Human ACVR2A (Accession P27037) fused with a C-His.
储存:
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
未开盖的干粉蛋白在 -20°C至-80°C可保存12个月;
复溶之后,蛋白溶液在-20°C及以下可保存3个月,在2-8℃可保存1周。
复溶:
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底,如果粉末浮起,开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL(请注意蛋白复溶浓度不能低于0.1 mg/mL),室温平衡5-10 min保证充分溶解,复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存,建议复溶时添加载体蛋白或者稳定剂(如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖),同时将复溶后的蛋白溶液按照需求进行分装,储存于-20°C至-80°C,随取随用,避免反复冻融。
