Recombinant Human Activin Receptor 2B/ACVR2B Protein (His Tag)

C-His

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

25-38 kDa

Activin proteins that belong to the transforming growth factor-beta (TGF-β) superfamily; exert their biological actions by binding to heteromeric receptor complexes of type I and type II serine/threonine kinase receptors. On ligand binding; type I and II receptors form a stable complex; resulting in phosphorylation of type I receptors by type II receptors with constitutive kinase activity; and subsequently initiates the activation of downstream molecules including the endogenous Smads. ActRIIB; also known as ActRIIB; is a type II receptor containing an extracellular domain (ECD); a transmembrane segment; and a cytoplasmic region that includes the kinase domain. ActRIIB is a receptor for activin A; activin B and inhibin A. Multiple ActRIIB isoforms can also be generated; which bind activin isoforms with different affinities.

< 1.0 EU per μg of the protein as determined by the LAL method.

Lyophilized from a 0.2 um filtered solution of 20mM PB, 150mM NaCl, pH 7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
