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.
产品描述
The Biosensis GDNF RapidTM 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 only if used as directed. Please refer to the kit protocol for specific use instructions for each substrate application. This ELISA kit consists of a pre-coated anti-GDNF capture antibody, a biotinylated anti-GDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3,5,5- tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of GDNF present in samples and protein standards. 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. Note that the antibodies used in this kit cross-react with guinea pig, rat and mouse GDNF. Guinea pig GDNF has been quantified in serum using the Human GDNF RapidTM ELISA kit, since guinea pig GDNF protein shares closest amino acid sequence homology with human GDNF. Protein levels can be expressed as œhuman GDNF equivalents. This kit has not been tested for other applications. It has been configured for research use only and is not to be used in diagnostic or clinical procedures.
