WebMar 1, 2024 · The fact that GFP has multiple excitation peaks suggests the presence of two distinct photogenic species in the chromophore. Indeed, the chromophore contains a slightly acidic phenol group. Both neutral phenol and anionic phenolate exist in the chromophore. It is estimated the ratio of phenol to phenolate is 6:1 in wild-type GFP.
