FMOC-Lys(QSY-21)-OH is a useful building block for labeling lysine with the quencher QSY-21 during peptide synthesis. It works well in developing FRET probes, especially when paired with dyes like Cy5, TF5, or iFluor 647, which have similar fluorescence spectra.
Applications:
- Peptide Synthesis:
Researchers often use FMOC-Lys(QSY-21)-OH to easily incorporate QSY-21 into peptides by labeling lysine. This helps in creating peptides for fluorescence-based experiments. - FRET Probe Development:
QSY-21 acts as an effective quencher in FRET probes. When paired with Cy5, TF5, or iFluor 647, it allows researchers to track molecular interactions and enzyme activities. - Fluorescence Assays:
By combining QSY-21 with specific fluorophores, researchers can develop assays for studying protein interactions and molecular processes. This setup enhances the accuracy of fluorescence-based studies.
Conclusion:
In summary, FMOC-Lys(QSY-21)-OH is essential for lysine labeling with QSY-21. Its ability to pair with Cy5, TF5, or iFluor 647 makes it a key tool in developing FRET probes and conducting fluorescence-based research.
