WebApr 10, 2024 · Stained sperm cells were imaged using a fluorescence microscope with blue (460–490 nm) and green (530–550 nm) excitations for SYBR-14 and PI. While SYBR-14 stains all cells in green, PI only enters cells and stains them red when membrane integrity is compromised. Thus, the ratio of red and green stained cells measures cell viability. WebIn gel electrophoresis, fluorescent nucleic acid gel stains are dyes used for DNA detection. When bound to DNA molecules and illuminated with UV or blue light, these dye molecules fluoresce brightly. Once the gel is stained, transilluminators are used to excite the dye molecules, which allow DNA to be visualized, sized, and quantified.
WebFor most nucleic acid stains, the fluorescent signal is minimal before binding to DNA or RNA, and there is a significant increase in fluorescence intensity after the dye has bound to DNA or RNA. All nucleic acid dyes have at least some affinity for both DNA and RNA. Some types of nucleic acid dyes are highly specific for the double-stranded DNA ... WebApr 12, 2024 · The basic premise of fluorescence microscopy is to stain the components with dyes. Fluorescent dyes, also known as fluorophores or fluorochromes, are molecules that absorb excitation light at a given wavelength (generally UV), and after a short delay emit light at a longer wavelength.
