Purity of recombinant human beta NGF 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 beta NGF (HZ-1222) stimulates dose-dependent proliferation of the TF-1 human erythroleukemic indicator cell line. Cell number was quantitatively assessed by Prestoblue® Cell Viability Reagent. TF-1 cells were treated with increasing concentration of recombinant beta NGF for 72 hours. The EC50 range is 0.5-3.00 ng/mL.

GMP recombinant human beta NGF (HZ-1222-GMP) stimulates dose-dependent proliferation of the TF-1 human erythroleukemic indicator cell line. Cell number was quantitatively assessed by Prestoblue® Cell Viability Reagent. TF-1 cells were treated with increasing concentration of recombinant beta NGF for 72 hours. Activity determination was conducted in triplicate on a validated bioassay. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 values range from 0.5-3.00 ng/mL.
