Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

GDNF (Glial cell-derived neurotrophic factor) is a protein that potently promotes the survival of many types of neurons. It signals through GFRα receptors, particularly GFRα1.  The recombinant form of this protein has been shown to promote the survival and differentiation of dopaminergic neurons in culture, and to prevent apoptosis of motor neurons induced by axotomy.  The most prominent feature of GDNF is its ability to support the survival of dopaminergic and motorneurons. These neuronal populations die in the course of Parkinson's disease and amyotrophic lateral sclerosis (ALS). GDNF also regulates kidney development and spermatogenesis, and it affects alcohol consumption.  GDNF has regenerative properties for brain cells and showed potential as treatment for Parkinson's disease. Diseases associated with GDNF include Hirschsprung Disease 3 and Congenital Central Hypoventilation Syndrome.
