Abstract
Glial cell-line derived neurotrophic factor (GDNF) is a secreted protein with great therapeutic potential. However, in order to analyse the interactions between GDNF and its receptors, researchers have been mostly dependent of radioactive binding assays. We developed a FACS-based binding assay for GDNF as an alternative to current methods. We demonstrated that the FACS-based assay using TGW cells allowed readily detection of GDNF binding and displacement to endogenous receptors. The dissociation constant and half maximal inhibitory concentration obtained were comparable to other studies using standard binding assays. Overall, this FACS-based, simple to perform and adaptable to high throughput setup, provides a safer and reliable alternative to radioactive methods.
