Growth Factors, Cytokines Storage: -20CShipping: Blue Ice
Human GDNF (Glial-Derived Neurotrophic Factor) is a 30.1kD protein that specifically promotes dopamine uptake and survival of midbrain neurons. GDNF is a disulphide-linked homodimer, formed by two identical 134aa subunits.

Source:
Recombinant corresponding to human GDNF expressed in E. coli.

Biological Activity:
The ED50 as determined by the dose-dependent dopamine uptake by rat ventral mesencephalic cultures was found to be in the range of 4-8ng/ml.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
~30.1kD
Source: E.coli
Purity: ~98% (SDS-PAGE and HPLC). Endotoxin: <0.1EU/ug
Concentration: Not determined
Form: Supplied as a lyophilized powder from 10mM sodium citrate, 150mM sodium chloride, pH 4. Reconstitute in sterile ddH2O to 0.1-1.0mg/ml.
