Correlative Live-Cell Imaging and Super-Resolution Microscopy of Autophagy
Abstract
Correlative live-cell imaging and super-resolution microscopy of autophagy was developed to combine the temporal resolution of time-lapse fluorescence microscopy with the spatial resolution of super-resolution microscopy. HEK293 cells that express recombinant proteins of interest fused to fluorescent tags are imaged live to capture the formation of autophagosomes, fixed on stage to "snap-freeze" these structures, stained with appropriate antibodies, relocated, and imaged at super resolution by direct stochastic optical reconstruction microscopy. This chapter provides an easy-to-follow protocol along with practical tips and background information to help set up and perform an experiment.

“A significant portion of LAMP1-labeled organelles lack major lysosomal hydrolases, and LAMP1 intensity is not a sensitive readout to assess autophagic deficits in familial amyotrophic lateral sclerosis-linked motor neurons in vivo [190,191].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
