Purity of recombinant human HGH was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.
Recombinant human HGH (HZ-1007) stimulates dose-dependent proliferation of the NB211 rat lymphoma cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. NB211 cells were treated with increasing concentrations of recombinant HGH for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.05-0.5 ng/mL.

Proteintech HGH (HZ-1007) demonstrates equivalent induction of proliferation and a 2-fold lower EC50 compared to leading competitors. Recombinant human HGH stimulates dose-dependent proliferation of the NB211 rat lymphoma cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. NB211 cells were treated with increasing concentrations of recombinant HGH for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.02-0.120 ng/mL.
