Human GDNF Rapid ELISA Assay

GDNF is a glycosylated, disulfide-bonded homodimer molecule. It was first discovered as a potent survival factor for midbrain dopaminergic neurons and was then shown to rescue these neurons in animal models of Parkinson's disease. GDNF is about 100 times more efficient survival factor for spinal motor neurons than the neurotrophins. FUNCTION: Neurotrophic factor that enhances survival and morphological differentiation of dopaminergic neurons and increases their high-affinity dopamine uptake. SUBUNIT: Homodimer; disulfide-linked. SUBCELLULAR LOCATION: Secreted protein. ALTERNATIVE PRODUCTS: 2 named isoforms produced by alternative splicing. DISEASE: Defects in GDNF may be a cause of Hirschsprung disease (HSCR) . In association with mutations of RET gene, defects in GDNF may be involved in Hirschsprung disease. This genetic disorder of neural crest development is characterized by the absence of intramural ganglion cells in the hindgut, often resulting in intestinal obstruction. DISEASE: Defects in GDNF are a cause of congenital central hypoventilation syndrome (CCHS) ; also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. SIMILARITY: Belongs to the TGF-beta family. GDNF subfamily.

The Biosensis GDNF Rapid enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the quantification of GDNF in less than 4 hours in cell culture supernatants, cell lysates, and guinea pig serum. This GDNF ELISA kit employs a recombinant human GDNF standard obtained from the National Institute for Biological Standards and Control (NIBSC) and is therefore designed to accurately measure the human form of GDNF. The antibodies used in this kit cross-react with guinea pig, rat and mouse GDNF.

Human. The antibodies used in this kit detect guinea pig, mouse and rat GDNF. No cross-reactivity was observed for the following proteins tested at 25 ng/mL in assay buffer: brain-derived neurotrophic factor (rhBDNF), nerve growth factor (rhNGF), neurotrophin-3 (rhNT-3), rhNT-4/5, vascular endothelial growth factor (rhVEGF), recombinant human Neurturin, Artemin and Persephin.
