WebSep 8, 2009 · Abstract. Static quenching and time-resolved emission spectra of tryptophan residues of BSA (2 Trp residues) and HSA (1 Trp residue) were performed in the presence of high concentrations of calcofluor white, a fluorophore that is specific to both carbohydrate residues and to hydrophobic sites in proteins. In the absence of calcofluor white, BSA ... WebAbstract. Herein we study the responses of two standard molecules, tryptophan and fluorescein, over a large concentration range in boric acid via two front-face fluorescence spectroscopies: excitation emission matrix fluorescence and laser-induced fluorescence. The responses in relation to the tryptophan content were measured and were found to …
