应用
Transforming growth factor-β1, human (hTGF-β1) has been used to explore function and underlying mechanism of periostin (PN) during orthodontic periodontal ligament remodeling.
生化/生理作用
Transforming Growth Factor-β1, human (hTGF-β1), is a multifunctional growth factor affecting many functions in a variety of different cells.
Transforming growth factor-β (TGF-β) family comprises of a group of multifunctional cytokines which are involved in controlling apoptosis, growth and differentiation of cells, and play important role during embryo development.

序列
Chain Length 2 x 112 AA
Two identical polypeptide chains (112 amino acids) connected by disulfide bridges, identical to natural hTGF-β1.
单位定义
EC50 definition: The concentration of hTGF-β1 that is required to mediate half maximal inhibition of DNA synthesis (BrdU incorporation) with Mv1-Lu cells.
制备说明
Working concentration: 0.01 - 10 ng/ml
Recombinant, human TGF-β 1 exerts its biological activity in the concentration range of 0.01–10 ng/ml.
Working solution: Dilute the concentrated TGF-β1 solution (1 μg/ml) with PBS or culture medium containing BSA [or HSA (human serum albumin)], 1 mg/ml (0.1%) or serum 1–10%.
Storage conditions (working solution): For best results, prepare appropriate aliquots and store at -15 to -25 °C.
Note: Avoid repeated freezing and thawing.
