WebFluorescence Microscopy. For researchers, the main benefit of fluorescence is the ability to use fluorescence microscopy, where samples are labeled/stained with a fluorescent substance such as a dye, antibody or protein, allowing images to have contrast. By targeting these fluorescent labels, researchers can select what they want to see. WebWe recently developed a convenient and versatile method that uses a gene-specific RNA aptamer and a fluorescent probe to enable spatiotemporal imaging of endogenous mRNAs in living cells. The method was validated by live-cell imaging of the endogenous mRNA of β-actin.
