Description
TGF beta 1/TGFB1 Protein is initially identified as a growth factor that induces the growth of rodent fibroblasts. TGF beta 1/TGFB1 Protein inhibits the cell cycle in the G1 phase. TGF beta 1/TGFB1 is an endogenous factor controlling apoptosis in normal and pathological tissues. TGF beta 1/TGFB1 Protein, Human (Biotinylated, HEK293, N-Avi) is a recombinant protein (A279-S390) produced by HEK293 cells with Avi tag[1][2].
Background
TGF beta 1/TGFB1 Protein (transforming growth factor beta 1) is a multifunctional cytokine, which is synthesized by almost all cells. TGF beta 1/TGFB1 Protein has a high ability to bind with TGFbRII[3].
The sequence of amino acids in TGFb1 proteins from different species is very stable, which leads to the conclusion that in the process of evolution, TGFb has been only slightly altered, and that both in humans and in animals, its function is similar.
TGF beta 1/TGFB1 Protein is secreted as an inactive peptide, forming part of a ‘latent complex’ consisting of a mature TGFB1 dimer non-covalently bound to its latency-associated peptide (LAP) and, via LAP, to latent TGFB-binding proteins (LTBPs). Activated TGF beta 1/TGFB1 Protein binds to ubiquitously expressed cell-surface TGFB1 type I receptors (TGFBRI) and type II receptors (TGFBRII), which are transmembrane serine/threonine kinases[4].
TGF beta 1/TGFB1 Protein regulates cell proliferation, growth, differentiation and cells movement. TGFb1 has immunomodulatory effects. TGF beta 1/TGFB1 Protein has profibrogenic effects. TGF beta 1/TGFB1 Protein action can be local and systemic. TGF beta 1/TGFB1 Protein plays a driving role in development, fibrosis and cancer[4].
In Vitro
TGFB1 human (0.2 ng/mL) upregulates LINC00941[5].
TGF-β1 (0.2 ng/mL) significantly and maximally inhibits the growth of MLE cells[6].
TGF–β1 (5 ng/ml) results in a significant increase in the protein and mRNA levels of IL-6 in HTM cells[7].
Verified Bioactivity
Measured by its ability to inhibit TGF-beta 1 activity on TF‑1 human erythroleukemic cells.The ED50 for this effect is 22.36-137.37 pg/mL.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of 50 mM Glycine-HCl, 150 mM NaCl, pH 2.5.
<0.01 EU/μg, determined by LAL method.
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).
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.
