We visualize GFP via immunofluorescence with an anti-GFP antibody. If we want to view the GFP directly in fixed cells, we have to use a different fixation procedure without acid, but with the addition of methanol. WebFixation of samples with cells producing fluorescent fusion proteins is commonly used for preservation of samples and for staining with membrane impermeable reagents such as antibodies. However, the effect of fixation methods and mounting media on fluorescence lifetime is poorly documented so far. relaxing view of nature
