QUANTIFICATION OF MITOCHONDRIAL MEMBRANE CURVATURE BY THREE-DIMENSIONAL LOCALIZATION MICROSCOPY.
iScience notes(2019)
摘要
Mitochondrial membrane organization is important for many biological functions, and is implicated in a number of diseases, but conventional microscopy has insufficient resolution to image biologically relevant structures. We present methods to quantify nanoscale membrane curvature using three-dimensional localization-based super-resolution microscopy. Localizations are analyzed using a cluster algorithm followed by principal component analysis to determine local membrane curvature. Results are shown for mitochondria in C2C12 mouse myotubes labeled with Tom20-Dendra2.
