Abstract
Förster (fluorescence) resonance energy transfer (FRET) is an ideal technique to estimate the distance between interacting protein molecules in live specimens using intensity-based microscopy. The spectral overlap of donor and acceptor- essential for FRET-also generates a contamination of the FRET signal. There are a number of algorithms available to remove this spectral bleedthrough (SBT) contamination and in this paper we compare two popular algorithms to estimate the SBT element and to calculate a more precise level of energy transfer efficiency, and with that a more accurate distance estimate.Entities:
