Description

Recombinant Protein

Measured in a cell proliferation assay using SH-SY5Y human neuroblastoma cells. The ED50 for this effect is 0.750-9.00 ng/mL in the presence of Recombinant Human GFR alpha -1/GDNF R alpha 1 Fc Chimera (Catalog # 714-GR ). The specific activity of recombinant human GDNF is >5.0 x 105 units/mg, which is calibrated against the human GDNF Reference Standard (NIBSC code: 09/266).
