Synonym
TGFB2, MGC116892, TGFβ2, TGF-beta2
Source
Human TGF-Beta 2, Tag Free (TG2-H4215) is expressed from human 293 cells (HEK293). It contains AA Ala 303 - Ser 414 (Accession # P61812-1).
Predicted N-terminus: Ala 303
Molecular Characterization
This protein carries no "tag".
The protein has a calculated MW of 12.7 kDa. The protein migrates as 23-25 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in TFA and ACN with trehalose as protectant.

Background
Transforming growth factor beta 2 ( TGFB2) is also known as TGF-β2, G-TSF, TGFB. is a polypeptide member of the transforming growth factor beta superfamily of cytokines. It is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation and apoptosis. The TGFB2 protein helps control the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). The TGFB2 protein can inhibit the T cell growth by IL-2-dependent. and can inhibit immune surveillance during tumor development, the protein promoting tumor growth with an autocrine manner. TGF-β2 can affect the viability of killer cells and reduce the expression of IL-2, IL-6, IL-10, IFN-γ and other cytokines.TGFB2 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages.
