|Product Overview:||Recombinant Human GDNF, Arg109-Ile211, was produced in NS0 cell under cGMP guidelines.|
|Form:||Lyophilized from a 0.2 μm filtered solution in PBS.|
|Bio-activity:||Measured in a cell proliferation assay using SH‑SY5Y human neuroblastoma cells.
The specific activity of recombinant human GDNF is approximately 3.1 x 10^3 units/μg, which is calibrated against recombinant human GDNF Reference Standard (NIBSC code: 09/266).
Measured by its binding ability in a functional ELISA. Immobilized Recombinant Human GFR alpha ‑1/GDNF R alpha ‑1 Fc Chimera at 1 µg/mL can bind Recombinant Human GDNF with an apparent Kd <1 nM.
|Molecular Mass:||Predicted Molecular Mass: 11.6 (monomer) kDa|
|N-terminal Sequence Analysis:||Arg109-Gly-Gln-Arg-Gly-Lys-Asn-Arg-Gly-(Cys)|
|Endotoxin:||<1.0 EU per 1 μg of the protein by the LAL method.|
