Purity

>97%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie庐 Blue Staining.

Endotoxin Level

<0.10 EU per 1 渭g of the protein by the LAL method.

Activity

Measured by its ability to inhibit the IL-4-dependent proliferation of HT2 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/渭g, which is calibrated

against human TGF beta 1 Standard (NIBSC code: 89/514).
