Product Description	Recombinant Human/Cynomolgus Activin RIIB/ACVR2B Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Ser19-Thr137 (Human) / Ser40-Thr158 (Cynomolgus).
Product Background	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).
