Glial derived Neurotrophic Factor Rat Recombinant produced in E.Coli is a homodimer, non-glycosylated, polypeptide chain containing 2 x 134 amino acids and having a total molecular mass of 29.8 kDa.
GDNF promotes the survival and differentiation of dopaminergic neurons in culture, and is able to prevent apoptosis of motor neurons induced by axotomy. The encoded protein is processed to a mature secreted form that exists as a homodimer. The mature form of the protein is a ligand for the product of the RET (rearranged during transfection) protooncogene. In addition to the transcript encoding GDNF, two additional alternative transcripts encoding distinct proteins, referred to as astrocyte-derived trophic factors, have also been described. Mutations in this gene may be associated with Hirschsprung disease.GDNF enhances survival and morphological differentiation of dopaminergic neurons and increases their high-affinity dopamine uptake.
It is recommended to reconstitute the lyophilized Glial Derived Neurotrophic Factor in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. Recombinant rat GDNF has full biological activity when compared to standards. The ED50, determined by a cell proliferation assay using rat C6 cells, is less than 0.2ng/ml corresponding to a specific activity of more than 5,000,000IU/mg.
