Steady-state cross-correlations for live two-colour super-resolution localization data sets

Nat Commun. 2015 Jun 12:6:7347. doi: 10.1038/ncomms8347.

Abstract

Cross-correlation of super-resolution images gathered from point localizations allows for robust quantification of protein co-distributions in chemically fixed cells. Here this is extended to dynamic systems through an analysis that quantifies the steady-state cross-correlation between spectrally distinguishable probes. This methodology is used to quantify the co-distribution of several mobile membrane proteins in both vesicles and live cells, including Lyn kinase and the B-cell receptor during antigen stimulation.
