Merck, ECM002-50UG, Thrombospondin-1 human

Thrombospondin-1 (TSP1) belongs to family of glycoproteins and possesses a complex trimeric structure. The structure comprises a heparin-binding domain and a procollagen homology domain located at the amino terminus, while the carboxyl-terminal end contains type I, II, and III repeats. This protein is manufactured in human cells using an all-human production system, with no serum. The human cells expression system allows human-like glycosylation and folding, and often supports better stability of the protein in culture. Recombinant human thrombospondin-1 is expressed in HEK293 cells as a glycoprotein with a calculated moleculaer mass of 127.5 kDa.
