Title
Fluorescence images of autophagosomes in living MEFs obtained in SIM mode for single-photon activation
Description
The autophagosomes labeled with the autophagy marker protein LC3B fused to Skylan-NS in living mouse embryonic fibroblasts (MEFs) in structured illumination microscopy (SIM) mode using single-photon activation. Fluorescence images of autophagosomes in living MEFs in SIM mode were captured. Skylan-NS is a photoswitchable green fluorescent protein . LC3B is to function in expansion of the autophagosomal membrane. CW laser is used for single-photon activation, which is more efficient and allows measurement with higher temporal resolution.

(Abstract) The background light from out-of-focus planes hinders resolution enhancement in structured illumination microscopy when observing volumetric samples. Here we used selective plane illumination and reversibly photoswitchable fluorescent proteins to realize structured illumination within the focal plane and eliminate the out-of-focus background. Theoretical investigation of the imaging properties and experimental demonstrations show that selective plane activation is beneficial for imaging dense microstructures in cells and cell spheroids.
