WebJan 19, 2024 · Metachromasia of anionic tissue can be demonstrated with many cationic dyes such as thiazine, oxamine, azine, and xanthene, and with fluorescent dyes such as Acridine orange. The thiazine dyes toluidine blue and Azure A are by far the most widely used. Metachromasia is best observed in a water solution of low ionic strength.

Fluorophores lose their ability to fluoresce as they are illuminated in a process called photobleaching. Photobleaching occurs as the fluorescent molecules accumulate chemical damage from the electrons excited during fluorescence. Photobleaching can severely limit the time over which a sample can be observed by fluorescence microscopy. Several techniques exist to reduce photobleaching such as the use of more robust fluorophores, by minimizing illuminatio… WebFor these reasons, fluorescent stains are often used in proteomics applications and on 2-D gels, where the relative quantitation of proteins in complex mixtures over several orders of abundance is performed and …
