WebApr 13, 2024 · A Bright Surprise: Live-Cell Labeling with Negatively Charged Fluorescent Probes based on Disulfonated Rhodamines and HaloTag. Dr. Dojin Kim, Dr. Dojin Kim. ... Disulfonated rhodamines are photostable and bright dyes widely used in life science and optical microscopy. However, di-sulfonated dyes were considered cell impermeable and … WebA single isomer derivative of fluorescein. FAM is the most commonly used fluorescent dye attachment for oligonucleotides and is compatible with most fluorescence detection equipment. It becomes protonated and has decreased fluorescence below pH 7; it is typically used in the pH range 7.5–8.5. FAM can be attached to 5' or 3' end of oligos.
