Description
Measured by its ability to inhibit the IL-4-dependent proliferation of HT-2 mouse T cells. Tsang, M. et al. (1995) Cytokine 7:389. The ED50 for this effect is 0.04-0.2 ng/mL. The specific activity of Recombinant Human TGF-beta 1 is approximately 2.5 x 104 U/μg, which is calibrated against human TGF-beta 1 Standard (NIBSC code: 89/514). Specific activity is for reference purposes only and is not routinely tested.Specifications
