| Description : |
Activin receptor type-2A (ACVR2A) is also known as activin receptor type IIA, ACTR-IIA, ACTRIIA, and ACVR2, and is a single-pass type I membrane protein. ACVR2A belongs to the protein kinase superfamily, the TKL Ser/Thr protein kinase family, and the TGFB receptor subfamily. Upon ligand binding, ACVR2A forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors, which then phosphorylate and activate SMAD transcriptional regulators. ACVR2A also serves as a receptor for activin A, activin B, and inhibin A (the latter in complex with betaglycan). Two type II activin receptors (ACVR2A and ACVR2B) have been identified, which bind different activins with distinct affinities. |
| Form : |
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant. |
| Bio-activity : |
Immobilized Human/Cynomolgus Activin RIIA Protein, His Tag at 1 μg/mL (100 μL/well) can bind Bimagrumab with a linear range of 0.05-1 ng/mL. |
| Molecular Mass : |
The protein has a calculated MW of 15.4 kDa. The protein migrates as 29-35 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation. |
| Endotoxin : |
Less than 1.0 EU/μg by the LAL method/rFC method. |
| Purity : |
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS. |
| Storage : |
This product is stable after storage at: -20 to -70 centigrade for 12 months in lyophilized state; -70 centigrade for 3 months under sterile conditions after reconstitution. For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower. Please avoid repeated freeze-thaw cycles. |
| Reconstitution : |
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 μg/μL. Centrifuge the vial at 4 centigrade before opening to recover the entire contents. |
