|Product Overview :
||ACVR2B contains C-terminal polyhistidine tag and has a calculated MW of 41 kDa. DTT-reduced protein migrates as 60 kDa polypeptide in SDS-PAGE.
||ACVR2B is an activin type 2 receptor. Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine/threonine specificity.
||Recombinant human ACVR2B (rhACVR2B) Ser19-Thr134 (Accession CAA54671) was produced in human HEK293 cells.
||Bulk protein in a 0.22 μm filtered solution of PBS, pH 7.4 and delivered as liquid formulation or lyophilized powder. Normally 5-8% trehalose and mannitol are added as protectants before lyophilization.
||>97% as determined by SDS-PAGE. All lots are greater than 97% pure.
||Less than 1.0 EU per 1 μg of the rhACVR2B by the LAL method.
||Stable in lyophilized state at 4°C for 1 year after receipt. Sterile stock solutions reconstituted are stable at 4°C for 2 months and at -20°C for 6 months. Avoid repeated freeze-thaw cycles.
