 Recombinant Human Glial Cell-derived Neurotrophic Factor
 GDNF
 ATF1, ATF2
 Astrocyte-derived trophic factor 
 Glial cell-derived neurotrophic factor (GDNF) is a small protein that promotes the survival of various neuronal subpopulations in both the central as well as the peripheral nervous systems at different stages of their development. GDNF is a founding member of the GDNF family of ligands (GFL) and has been shown to interact with GFRA2 and GDNF family receptor alpha 1. GDNF (monomer) contains seven conserved cysteine residues, one of which (Cys 101) is used for inter-chain disulfide bridging and the others are involved in intramolecular ring formation known as the cystine knot configuration.

 Storage/Handling: This lyophilized  preparation is stable at 2-8°C, but should be kept at -20°C for long term storage.  The reconstituted sample can be apportioned into working aliquots and stored  at -80 °C for up to 6 months. Avoid repeated freeze/thaw cycles. 
 Reconstitution: The sample should  be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute  in a siliconized tube using PBS that contains a 0.1% BSA to a concentration of  0.1-1.0 mg/mL. Reconstituted solutions are stable for up to one week at 2-8°C.  Stock solutions should be aliquoted and stored at -80°C. Further dilutions should  be made in appropriate buffered solutions.
