CellGenix® rh TGF-β1

Preclinical grade

CellGenix Recombinant Human TGF-β1 reliably promotes the expansion of induced pluripotent stem cells, embryonic stem cellsas well as mesenchymal stem cells. It also stimulates the differentiation of T cells into regulatory T cells and the expansion of regulatory T cells. Proper glycosylation of TGF-ß1 is of significant importance for the protein’s processing and functional expression – one of the reasons why production of this growth factor and certain complexly glycosylated proteins is not feasible using conventional bacterial expression systems.

General Information

Transforming Growth Factor-beta 1 (TGF-β1) is a member of the growth factor beta superfamily and plays a role in various cellular functions like cell differentiation, proliferation and apoptosis. It is secreted by most immune cells and especially interacts with T cells, B cells, macrophages and monocytes.

CellGenix Recombinant Human TGF-β1 is produced using a human amniocyte cell line (CAP®). By using the CAP® technology we are able to produce this difficult to express glyco-protein with authentic human post-translational modifications. These human post-translational modifications are not accessible by bacterial expression.
