Applications: Useful for studying protein binding and screening small molecular inhibitors
Description: Human secreted CD137, Fc fusion protein, also known as Tumor Necrosis Factor Receptor Superfamily member 9, TNFRSF9, and ILA, GenBank Accession No. NM_001561, a.a. 24-186, expressed in a HEK293 cell expression system, fused at the C-terminus to the Fc portion of human IgG1 and enzymatically biotin-labeled using Avi-tag™ technology. MW = 45.9 kDa (monomer). Biotinylation is confirmed to be >90%. This protein runs at a higher MW by SDS-PAGE due to glycosylation.
