The tag is some kind of fluorescent molecule (also known as fluorophore). However, in this particular case, it was simply a reaction to a dye used in ophthalmology and absorbed by contact lenses. Reactive fluorescent dyes are widely used to modify amino acids, peptides, proteins (in particular, antibodies), oligonucleotides, nucleic acids, carbohydrates and other biological molecules. The remainder of this chapter will focus on the use of fluorescent proteins as the reporter of choice, but many discussion points also apply to the use of fluorescent dyes.

Ram Sabnis organizes the compounds alphabetically by the Fluorescent tag In molecular biology and biotechnology, a fluorescent tag is a part of a molecule that researchers have attached chemically to aid in detection of the molecule to which it has been attached. Fluorochromes can include advanced types such as Alexa Fluor dyes, quantum dots, and fluorescent proteins, as well as molecular probes designed for specific detection. Importantly, all Alexa dyes are sulfonated forms of different basic fluorescent substances, so they are often similar to standard dyes in their excitation and emission maxima (Table 2). Fluorescent disperse dyes on polyester and cationic dyes on acrylic fibres show technical performance characteristics typical of the dye application class. , green fluorescent protein, phycoerythrin, allophycocyanin) and quantum dots.

Ultimately, emerging from the hospital with fluorescent green eyes might sound like a scene from fiction. cence instrumentation. A similar concept can be applied to plants because the dye can make problems in plant vasculature more visible. Their ability to absorb light, re-emit it at a longer wavelength, and provide high-contrast signals makes them essential in techniques like fluorescence microscopy, flow cytometry, and molecular assays. Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds.
