Quantitative microscopy based on single-molecule fluorescence.

Quantitative microscopy based on single-molecule fluorescence. Curr Opin Chem Biol. 2017 Jun 14;39:64-73 Authors: Jung SR, Fujimoto BS, Chiu DT Abstract Quantitative microscopy is needed to understand reactions or phenomena carried out by biological molecules such as enzymes, receptors, and membrane-localized proteins. Counting the biomolecules of interest in single organelles or cellular compartments is critical in these approaches. In this brief perspective, we focus on the development of quantitative fluorescence microscopies that measure the precise copy numbers of proteins in cellular organelles or purified samples. We introduce recent improvements in quantitative microscopies to overcome undercounting or overcounting errors in certain conditions. We conclude by discussing biological applications.
