名称:重组人Activin receptor type-2B/ACVR2B Protein(C-Fc-6His);
产品说明(Description) Recombinant Human Activin Receptor Type 2B is produced by our Mammalian expression system and the target gene encoding Ser19-Thr134 is expressed with a Fc, 6His tag at the C-terminus. Accession #: Q13705 Known as: Activin Receptor Type-2B; Activin Receptor Type IIB; ACTR-IIB; ACVR2B 制剂(Formulation) Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4. 质量控制(Quality Control) Bioactivity* Measured by its ability to bind Human Activin A in functional ELISA. The ED50 for this effect is less than 100 ng/ml Purity: Greater than 95% as determined by reducing SDS-PAGE. Endotoxin: Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. 复溶(Reconstitution) Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 保存(Storage) Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. 背景(Background) 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. 电泳(SDS-PAGE) FOR RESEARCH USE ONLY
