Description: Glial derived Neurotrophic Factor Human Recombinant produced in E.Coli is a non-glycosylated disulfide-linked homodimer containing 2 x 135 amino acids and having a total molecular mass of approximately 30kDa. GDNF is purified by proprietary chromatographic techniques.

Protein Derived From: Escherichia Coli.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Purity: Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Stability: Lyophilized Glial-derived Neurotrophic Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution GDNF should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

Biological Activity: The ED50 was determined by the proliferation of rat C6 cells is < 0.1 ng/ml, corresponding to a specific activity of > 1.0x107 units/mg.

Solubility: It is recommended to reconstitute the lyophilized Glial Derived Neurotrophic Factor in sterile 18MOmega-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
