Inhibition of IL-4-induced HT-2 cells proliferation assay for Human TGF-β1. Cell proliferation was measured to calculate the ED50, which is as expected less than 500 pg/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Human TGF-β1 has a predicted Mw of 25.6 kDa (each monomer is 12.8 kDa).

Transforming Growth Factor β 1 (TGF-β1) is a member of the TGF-β superfamily of cytokines. Members of this family exhibit regulatory activity in immunity, proliferation, adhesion, migration, and growth inhibition pathways. TGF-β1 signals through SMAD proteins via the TGF-β RI and TGF-β RII receptors.

Activity Assay

Human TGF-β1 is fully biologically active when compared to standard. The activity is determined by the ability to inhibit IL-4-induced HT-2 cells proliferation and it is typically less than 500 pg/ml. This corresponds to an expected specific activity of 2 x 106 units/mg.
