Predicted Molecular Mass:8.2 kDa Activity:Measured by its ability to inhibit human FGF-basic-dependent proliferation of NR6R‑3T3 mouse fibroblast cells. Rizzino, A. et al. (1988) Cancer Res. 48:4266; Thomas, K. et al. (1987) Methods Enzymol. 147:120; Watson, J.B. et al. (1994) J. Clin. Invest. 94:261.The ED₅₀ for this effect is typically 5-15 µg/mL.Measured by its ability to bind Recombinant Human VEGF 165 (Catalog# 293-VE). Gengrinovitch, S. et al. (1995) J. Biol. Chem. 270:15059.The ED₅₀ for this effect is typically 0.5 - 2 µg/mL. Formulation:Lyophilized from a 0.2 µm filtered solution in PBS.See Certificate of Analysis for details. Molecule Information: CXCL4/PF4 Aliases: PF4 Entrez Gene IDs: 5196 (Human); 56744 (Mouse) Background: CXCL4/PF4 (Platelet Factor 4) Platelet factor 4 (PF4) is a member of the CXC chemokine family. Human and mouse PF4 share 64% identity. PF4 is involved in monocyte survivial and differentiation into macrophages, and it has anti-angiogenic activity.
