FITC Tau-441

While some fluorescent tau on the market uses intrinsic fluorescence and adds in tryptophan residues by mutations, rPeptide’s human tau-441 has been covalently labeled with Fluorescein Isothiocyanate and assayed for fluorescence. The FITC label has a maximum absorbance at 495 and a maximum emission at 525nm. This FITC labeled form of tau-441 is ideally suited to localization experiments, aggregation monitoring and binding kinetics without the need for mutations or further labeling.
