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

Cat. No.: HY-P73616
COA Handling Instructions

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, His) is the recombinant human-derived TGF beta 1/TGFB1 Latency-associated peptide protein, expressed by HEK293 , with C-10*His labeled tag and C33S mutation.

Description

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.

Background

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].

Biological Activity

Measured by its ability to inhibit TGF-beta 1 activity on HT‑2 mouse T cells. The ED50 this effect is ≤0.04393 μg/mL in the presence of 1 ng/mL of Recombinant Human TGF beta 1, corresponding to a specific activity is ≥2.276×104 units/mg.

Molecular Weight

Approximately 40-57 kDa due to the glycosylation.

Purity
  • Greater than 95% as determined by reducing SDS-PAGE.
Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years. 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.

Shipping

Room temperature in continental US; may vary elsewhere.

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.

  • Specific Activity Calculator

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
