Mouse transforming growth factor beta receptor 2 (TGFβR2), also known as TGFBR2, TGFR-2, and TGF-Beta Receptor Type 2, GenBank Accession No. NM_009371, a.a. 24-184 fused at the C-terminus of the Fc portion of human IgG1, with C-terminal Avi-tag, expressed in a HEK293 cell expression system, MW = 47 kDa. This protein runs at a higher molecular weight due to glycosylation.
