Abstract

The authors demonstrate that the fluorescence lifetime of certain fluorescent labels is a useful parameter to detect affinity binding between biotin and streptavidin, as well as between biotinylated bovine serum albumin and streptavidin. The assay is performed in a microplate format, and lifetimes are determined using dye laser-induced fluorescence. Four fluorescent labels are presented that ...
