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.

WebT-sapphire has a bleaching half-life (t½; time for an initial emission rate of x photons/s to reduce to half) of 25 seconds, but EGFP is much more stable, with a bleaching t½ of 174 seconds 4. Environmental conditions. Like most proteins, FPs are affected by pH, temperature, and oxygen levels.

WebGFP is a barrel shape with the fluorescent portion (the chromophore) made up of just three amino acids. When this chromophore absorbs blue light, it emits green fluorescence. Figure 1: The structure of GFP from the side and top. GFP is a hollow barrel shape with a chromophore in the center (the fluorescent portion).
