WebBy spatially controlling the light-exposure time, CLEM reduces the excitation-light dose without compromising image quality. We show that CLEM reduces photobleaching sevenfold in tobacco plant cells expressing microtubule-associated GFP-MAP4 and reduces production of reactive oxygen species eightfold and prolongs cell survival sixfold in HeLa ... WebThis does not affect a majority of the visible light optical microscopy done with immersion media, but it can lead to trouble when attempting to image specimens at wavelengths below 400 nanometers. The ultraviolet absorption of glycerin is negligible in the 400-350 nanometer region, so the pure solvent, or a 90:10 mixture with water, could be ...
