TGF beta 1/TGFB1 LAP Protein, Human (HEK293)

TGF beta 1/TGFB1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. TGF beta 1 is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation, apoptosis, and can regulate the expression and activation of other growth factors, including interferon gamma and tumor necrosis factor alpha. TGF beta 1/TGFB1 LAP Protein, Human (HEK293) is the recombinant human-derived TGF beta 1/TGFB1 LAP protein, expressed by HEK293 , with tag free. and C33S mutation.

Transforming growth factor (TGF) beta 1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines. TGF beta 1 is a secreted protein that performs many cellular functions, including the control of cell growth, cell proliferation, cell differentiation, apoptosis, and can regulate the expression and activation of other growth factors, including interferon gamma and tumor necrosis factor alpha. In humans, TGF-β1 is encoded by the TGFB1 gene. TGF beta 1 activates CREB3L1 by regulating intramembranous proteolysis, stimulating sustained collagen production. TGF beta 1 mediates SMAD2/3 activation by inducing SMAD2/3 phosphorylation and subsequent translocation to the nucleus and regulates dental papilla cells by promoting IPO7-mediated translocation of phosphorylated SMAD2 to the nucleus and subsequent transcription of target genes. TGF beta 1 induces epithelial-to-mesenchymal transition (EMT) and cell migration in various cell types.TGF beta 1 plays an important role in controlling the immune system, and shows different activities on different types of cell, or cells at different developmental stages^{[1][2][3][4][5][6]}.

1.Measured by its ability to inhibit TGF-β1 activity on HT-2 mouse T cells. The ED₅₀ this effect is 20-150 ng/mL in the presence of 1 ng/mL TGF-β1.
2.Measured by its ability to inhibit the IL-4-dependent proliferation of HT-2 mouse T cells.The ED₅₀ for this effect is 0.01185 ng/ml, corresponding to a specific activity is 8.43×10⁴ units/mg.

Lyophilized powder

1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.
Please refer to the lot-specific COA for specific buffer information.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in PBS. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
