Abstract

The rate constants for slow transitions between two states, which are characterized by different lifetimes of a fluorescent probe in the conformational interconversion of individual molecules in condensed phase, are measured by using single-molecule fluorescence spectroscopy. The sampling error for the estimates are derived based on the assumption that the data are gathered on M molecules, each monitored for a time T.

Abstract

A method for estimating rate constants of a two-state Markov system from data obtained by a single-molecule (SM) type of experiment corrupted by white noise is described. The method is effective even when the characteristic (or resolution) time of the measurement is much longer than a characteristic time of the two-state system, and the data are uncorrelated.
