TGF beta 2/TGFB2 Protein, Canine (HEK293, His)

Cat. No.: HY-P73614
Handling Instructions

Transforming growth factor-beta 2 (TGF-β2), an extracellular glycosylated protein, is a member of the TGF-β superfamily. TGFβ2 controls key physiological processes including cell migration, proliferation and differentiation via signalling through type I and type II receptors (TGFβR1 and TGFβR2). TGF-β2 is an immune suppressor involved in the development of immune tolerance, and also regulates embryonic development. TGF beta 2/TGFB2 Protein, Canine (HEK293, His) is produced in HEK293 cells  with a C-Terminal His-tag. It and consists of 414 amino acids (M1-S414).

Description

Transforming growth factor-beta 2 (TGF-β2), an extracellular glycosylated protein, is a member of the TGF-β superfamily. TGFβ2 controls key physiological processes including cell migration, proliferation and differentiation via signalling through type I and type II receptors (TGFβR1 and TGFβR2). TGF-β2 is an immune suppressor involved in the development of immune tolerance, and also regulates embryonic development[1][2]. TGF beta 2/TGFB2 Protein, Canine (HEK293, His) is produced in HEK293 cells  with a C-Terminal His-tag. It and consists of 414 amino acids (M1-S414).

Background

In mammals, three different isoforms of TGF-β are described (TGF-β1, TGF-β2 and TGF-β3; transforming growth factor beta) to regulate apoptosis, proliferation, differentiation, migration and invasion processes utilising overlapping but not redundant mechanisms. All three isoforms are expressed in the liver, but their expression is differentially distributed among liver cell types. TGF-β2 expression in different liver cell types and is also associated with developmental defects and fibrotic diseases in mice[1][2][3].
The sequence of amino acids in TGF-β2 proteins from different species is very stable, which leads to the conclusion that in the process of evolution, TGF-β2 has been only slightly altered, and that both in humans and in animals, its function is similar.
TGFβ2 is a transforming growth factor beta (TGFB) family cytokine, with members of this cytokine family playing broad regulatory roles and controlling key physiological processes including cell migration, proliferation and differentiation via signalling through type I and type II receptors (TGFβR1 and TGFβR2), with signals propagating via the downstream regulatory SMAD proteins. This TGFβ/SMAD pathway is frequently dysregulated in human cancer. TGFβ cytokines are capable of suppressing T cell growth in response to IL‐2. The degree of TGFβ2 expression correlated with the expression of several different markers of immune cell subsets within tumours. In addition, TGF-β2 regulates embryonic development and, therefore not surprisingly, global Tgfb2 null mice exhibit a wide range of developmental defects and perinatal mortality[1][2][3].
TGF-β2 is an immune suppressor involved in the development of immune tolerance, and recombinant TGF-β2 incubation is more potent than TGF-β1 or TGF-β3 in suppressing macrophage inflammatory responses. TGF-β2 is shown to correlate with bad prognosis in intrahepatic CCAs and hepatocellular carcinoma. Mechanistically, canonical Smad signalling as well as crosstalk with Yap, Hippo, Wnt and β-catenin signalling have been demonstrated in the liver and other organs[1][2][3].

In Vitro

Recombinant human TGF-β2 (1.25, 2.5, 5, 1, and 2 ng/mL; for 24 h) increases extracellular matrix (ECM) protein synthesis and secretion in optic nerve head (ONH) astrocytes and lamina cribrosa (LC) cells. TGF-β2 induces phosphorylation of canonical signaling proteins Smad2/3 but does not alter phosphorylation of non-canonical signaling proteins ERK1/2, p38, and JNK1/2 proteins in ONH astrocytes and LC cells[4].

In Vivo

Recombinant human TGF-β2 (12 μg/dog; for 28 days; porous-coated titanium implant) increases in fixation strength and stiffness of the implant in a canine model[5].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
