Source:
Optimized DNA sequence encoding Human Transforming Growth Factor Beta-2 mature chain was expressed in CHO Cells

 
Molecular weight:

Native human TGF-b2, generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 26 kDa.

Recombinant  Transforming Growth Factor Beta-2 is a homodimer protein consisting of 2x112 amino acid residue subunits. TGF-beta 2 migrates as an approximately  12 - 13 kDa protein under reducing conditions in SDS-PAGE and as 26kDa band under non reducing conditions.


 
Purity:
>95%, as determined by SDS-PAGE and HPLC.

TGF-beta 2

TGF-beta is the prototype of a protein family known as the TGF-beta superfamily. This family includes Inhibins, Activin A, MIS (Müllerian inhibiting substance), BMP (bone morphogenetic proteins), dpp (decapentaplegic) and Vg-1. Type 1 receptors and type 2 receptors have a molecular mass of 53 and 75 kDa, respectively. Signaling through the receptor requires heterodimeric complexes between both types of receptors. The type 2 receptor has been shown to bind the ligand, but it is incapable of mediating TGF- beta responses in the absence of the type 1 receptor. The type 1 receptor is expressed predominantly in hematopoietic progenitor cells. The type 2 receptor encodes a protein with an intracellular domain that functions as a serine/threonine kinase. TGF-beta is the most potent known growth inhibitor for normal and transformed epithelial cells, endothelial cells, fibroblasts, neuronal cells, lymphoid cells and other hematopoietic cell types. TGF-beta inhibits the proliferation of T- lymphocytes by down- regulating predominantly IL- 2 mediated proliferative signals. It also inhibits the growth of natural killer cells in vivo and deactivates macrophages. TGF-beta blocks the antitumor activity mediated in vivo by IL-2 and transferred lymphokine- activated or tumor infiltrating lymphocytes.
