Recombinant Human Activin ACVR1B protein, Fc-tagged

• Cat.No.: ACVR1B-332H
• Product Overview: Recombinant Human ACVR1B protein (Ser24-Glu126), fused to human IgG1 Fc tag at C-terminus, was expressed in human 293 cells (HEK293).

Specification

• Description: Activin receptor type-1B (ACVR1B) is also known as Activin receptor-like kinase 4 (ALK-4), Serine/threonine-protein kinase receptor R2 (SKR2), which belongs to the protein kinase superfamily, TKL Ser/Thr protein kinase family and TGFB receptor subfamily. ACVR1B contains one GS domain and one protein kinase domain. The catalytic activity of ACVR1B is "ATP + [receptor-protein] = ADP + [receptor-protein] phosphate". ACVR1B acts as a transducer of activin or activin like ligands (e.g., inhibin) signals. Activin binds to either ACVR2A or ACVR2B and then forms a complex with ACVR1B. These go on to recruit the R-SMADs SMAD2 or SMAD3. ACVR1B also transduces signals of nodal, GDF-1, and Vg1.
• Source: HEK293
• Species: Human
• Tag: human IgG1 Fc
• Form: Lyophilized from 0.22 um filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5, 10% trehalose.
• Molecular Mass: The protein has a calculated MW of 38.1 kDa. As a result of glycosylation, the protein migrates as 43-46 kDa under reducing (R) condition, and 85-90 kDa under non-reducing (NR) condition (SDS-PAGE).
• Protein length: 103
• Endotoxin: Less than 1.0 EU per ug by the LAL method.
• Purity: >92% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20 centigrade or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage at:
  -20 centigrade to -70 centigrade for 12 months in lyophilized state;
  -70 centigrade for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
