Description
Principle of the assay: human GDNF ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for GDNF has been precoated onto 96-well plates. Standards (NSO,R109-I211) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for GDNF is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human GDNF amount of sample captured in plate.
Background: Glial cell line-derived neurotrophic factor (GDNF) is a glycosylated, disulfide-bonded homodimer that is a distantly related member of the transforming growth factor-beta superfamily.1 GDNF, is a potent neurotrophic factor thatpromotes the survival of dopaminergic neurones in cultures including embryonic neuronal cultures.2 GDNF, inaddition to its potential role in the differentiation and survival of central nervous system neurons, has profound effects on kidney organogenesis and the development of the peripheral nervous system.3 GDNF may have utility inthe treatment of Parkinson's disease, which is marked by progressive degeneration of midbrain dopaminergic neurons.1 GDNF lies on the short arm of human chromosome 5, at 5p13.1-p13.3 ability to promote dopamineuptake in midbrain cultures.2
