Validation Data Gallery

  • Purity of recombinant human PTN 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.

  • GMP-grade recombinant human PTN (HZ-1278) stimulates dose-dependent proliferation of the THP-1 monocyte cell line. Viable cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. THP-1 cells were treated with increasing concentrations of recombinant PTN for 120 hours. The EC50 was determined using a 4-parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 values range from 120-650 ng/mL​.

Background

Pleiotrophin is a secreted growth factor that induces neurite outgrowth being mitogenic for fibroblasts, epithelial, and endothelial cells. It binds anaplastic lymphoma kinase (ALK) inducing MAPK pathway activation, as an important step in the anti-apoptotic signaling of PTN and cell proliferation (PMID:1768439; 1733956; 11278720)
