Tryptophan intrinsic fluorescence
Webdue to its size fluorescence polarization values obtained using intrinsic fluorescence will be high. Conversely, the amino acid tryptophan is quite small and would be expected to have a low polarization value in solution. Figure 2 demonstrates the ability of the Synergy H1 with UV-capable polarizers to distinguish different molar ratios WebTryptophan and tyrosine are hydrophobic and hydrophilic aromatic amino acids respectively, which are also known for their intrinsic fluorescence nature in proteins. By observing the autofluorescence of both these hydrophobic and hydrophilic amino acids upon SDS treatment, information about SDS-protein interactions could be obtained.
