Synonym(s): hTGF-β3; TGF-β3
Purity: ≥97% (SDS-PAGE)
Physical form: Lyophilized from a 0.2 μm filtered solution in 35% acetonitrile and 0.1% trifluoroacetic acid containing 50 μg bovine serum albumin per 1 μg of cytokine.
Analysis Note: The biological activity is measured by its ability to inhibit the IL-4-dependent proliferation of mouse HT-2 cells.
Storage: −20°C
Biochem/physiol Actions: TGF-β3 is less prevalent in natural expression than either TGF-β1 or TGF-β2, but it is the most abundant mRNA expressed in chick embryos. It is also expressed in human umbilical cord, in a variety of mesenchymal cells of human and rodent origin, and in several human carcinoma cells.
Empirical Formula (Hill Notation): C11H11NO2
