Assay Principle
This EZ-Set™ kit supplies a matched capture and detection antibody pair and a standard for building your own sandwich ELISA for human glial cell line-derived neurotrophic factor (gene GDNF) in cell culture supernatants, cell lysates, serum and plasma (heparin, EDTA). You coat the plate with the capture antibody, add samples and standards, detect with the biotinylated antibody and an avidin–biotin–peroxidase complex, develop with TMB and read at 450 nm. Plates, diluents, wash buffer, TMB and stop solution are not included.
Glial cell line-derived neurotrophic factor (GDNF) is a secreted growth factor that strongly supports the survival of dopaminergic and motor neurons. It binds the coreceptor GFRα1 and signals through the RET tyrosine kinase. GDNF is also required for kidney development and spermatogonial stem cell maintenance, and it is studied in Parkinson's disease research.
