Used extensively in fluorescence labeling and imaging techniques, it is particularly valuable in biological research for tagging proteins, antibodies, and other biomolecules. Its high fluorescence intensity and stability make it ideal for tracking cellular processes, studying molecular interactions, and visualizing structures in microscopy. It is also employed in flow cytometry to analyze and sort cells based on specific markers. Additionally, it serves as a key component in diagnostic assays, enabling the detection of target molecules with high sensitivity and specificity. Its versatility and reliability have made it a staple in both research and clinical applications.
