Statistical tests for measures of colocalization in biological microscopy.
Colocalization analysis is the most common technique used for quantitative analysis of fluorescence microscopy images. Several metrics have been developed for measuring the colocalization of two probes, including Pearson's correlation coefficient (PCC) and Manders' correlation coefficient (MCC). However, once measured, the meaning of these measurements can be unclear; interpreting PCC or MCC va...
متن کاملA practical guide to evaluating colocalization in biological microscopy.
Fluorescence microscopy is one of the most powerful tools for elucidating the cellular functions of proteins and other molecules. In many cases, the function of a molecule can be inferred from its association with specific intracellular compartments or molecular complexes, which is typically determined by comparing the distribution of a fluorescently labeled version of the molecule with that of...

15 صفحه اولColocalization analysis in fluorescence microscopy.
The measurement of colocalization requires images of two fluorophores that are aligned, with no cross talk, and that the intensities remain within the response range of the microscope. Quantitation depends upon differentiating between the presence and absence of fluorescence, and measurements should be made within biologically relevant regions of interest. Co-occurrence can be measured simply b...
متن کاملCryogenic colocalization microscopy for nanometer-distance measurements.
The main limiting factor in spatial resolution of localization microscopy is the number of detected photons. Recently we showed that cryogenic measurements improve the photostability of fluorophores, giving access to Angstrom precision in localization of single molecules. Here, we extend this method to colocalize two fluorophores attached to well-defined positions of a double-stranded DNA. By m...
