Purity of recombinant TGF beta 1 was determined by SDS-polyacrylamide gel electrophoresis. The protein was resolved in an SDS-polyacrylamide gel in reducing and non-reducing conditions followed by staining with Comassie blue.

Recombinant human TGF beta 1 (HZ-1011) inhibits IL-4 induced proliferation of the HT-2 mouse cell line. HT-2 cells are Balb/c spleen cells activated by sheep erythrocytes in the presence of IL-2. Cell number was quantitatively assessed by PrestoBlue® cell viability reagent. HT-2 cells were treated with increasing concentrations of recombinant TGF beta 1 for 72 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.01-0.17 ng/mL.
