Biotinylated Human/Cynomolgus Activin RIIB/ACVR2B Protein
Recombinant Biotinylated Human/Cynomolgus Activin RIIB/ACVR2B Protein is expressed from HEK293 with hFc tag and Avi tag at the C-terminus.It contains Ser19-Thr137 (Human) / Ser40-Thr158 (Cynomolgus) [Accession | Q13705-1(Human) / XP_045242398.1(Cynomolgus)].
The protein has a predicted MW of 41.41 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result.
> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC
Less than 1EU per μg by the LAL method.
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

ActRIIB (activin receptor type-2B) is an activin receptor subtype constitutively expressed in the whole body, playing a role in cellular proliferation, differentiation, and metabolism. For its various physiological activities, ActRIIB interacts with activin and multiple other ligands including myostatin (MSTN), growth differentiation factor 11 (GDF11), and bone morphogenetic protein 9 (BMP9).
