Description:

Recombinant Rat GDNF is a homodimeric protein consisting of two 134 amino acid non-glycosylated polypeptide chains.

Background: Glial cell-derived neurotrophic factor, also known as GDNF is a small protein that potently promotes the survival morphological differentiation of various neuronal which is encoded by the GDNF gene. Furthermore, it may also modulate local neuronal effects in distal regions of the motor neuron. In addition, 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. Recombinant rat GDNF (monomer) contains 135 amino acids residues, which is a disulfide-linked homodimer and it shares 99 % and 93 % aa sequence identity with mouse and human GDNF.

Reconstitution:

Centrifuge vial prior to opening. Add sterile distilled water or aqueous buffer to a concentration of 0.1-1.0 mg/ml. Further dilutions should be made in appropriate buffered solutions.

Storage/Stability:

This lyophilized preparation is stable at 2-4°C, but should be kept desiccated at -20°C for long term storage. Upon reconstitution, the preparation is stable for up to one week at 2-4°C.
