WebApr 1, 2024 · Intrinsic (tryptophan) fluorescence: conformational analysis Protein intrinsic fluorescence can be used to evaluate the change in its functional, structural, and physicochemical properties [ 51 ]. Therefore, it can be used to monitor the formation of HEWL amyloid fibrils. The fluorescence of a folded protein is a mixture of the fluorescence from individual aromatic residues. Most of the intrinsic fluorescence emissions of a folded protein are due to excitation of tryptophan residues, with some emissions due to tyrosine and phenylalanine; but disulfide bonds also have appreciable absorption in this wavelength range. Typically, tryptophan has a wavelength of maximum absorption of 280 nm and an emission peak that is solvatochromic, ran…
