Human transforming growth factor beta receptor 2 (TGFβR2), also known as TGFBR2, TGFR-2, and TGF-Beta Receptor Type 2, GenBank Accession No. NM_003242 (var2), a.a. 23-166 fused at the C-terminus of the Fc portion of human IgG1, with C-terminal Avi-tag, expressed in a HEK293 cell expression system and enzymatically biotinylated using Avi-tag™ technology. Biotinylation is confirmed to be ≥90%. MW = 45 kDa. This protein runs at a higher molecular weight due to glycosylation.
