A Fluorescence Fluctuation Spectroscopy Assay of Protein-Protein Interactions at Cell-Cell Contacts
Published on: December 1, 2018
Abstract:
Fluorescence correlation spectroscopy (FCS) has become a powerful and sensitive tool in biochemistry and biophysics. It directly obtains physical parameters such as the average number of fluorescent molecules and their diffusion time in a tiny detection area. It also provides other useful information such as the brightness of molecules. Ultimately, it can give precise information about molecular interactions in the aqueous condition. This protocol outlines the basic FCS setup and how measurements are made.
