Descripción
Measured in a cell proliferation assay using HUVEC human umbilical vein endothelial cells. Conn, G. et al. (1990) Proc. Natl. Acad. Sci. USA 87:1323. The ED50 for this effect is 1-6 ng/mL. The specific activity of recombinant human VEGF165 is approximately 1.7 x 103 U/μg, which is calibrated against recombinant human VEGF165 WHO Standard (NIBSC code: 02/286). Specific activity is for reference purposes only and is not routinely tested.
