Research output: Book/ReportBook

Abstract

In this unit on fluorescence recovery after photobleaching (FRAP), an imaging approach to study protein-protein interactions in situ is described. The protocols presented use confocal microscopy to examine the mobility of a fluorescent protein by measuring the recovery of the protein in a bleached area. The data gained in FRAP studies is qualitative and yields insight into relative binding affinity, binding characteristics, and the effect of treatments or mutations on protein mobility.
