BDP FL-PEG5-azide is widely used in bioconjugation and labeling applications due to its azide functional group, which allows for efficient click chemistry reactions. It is particularly valuable in the development of fluorescent probes for imaging and tracking biological molecules in live cells or tissues. The PEG5 spacer enhances solubility and reduces steric hindrance, making it suitable for attaching to proteins, peptides, or other biomolecules without disrupting their function. This chemical is also employed in the synthesis of drug delivery systems, where it can be used to conjugate targeting ligands or therapeutic agents. Additionally, its fluorescent properties enable real-time monitoring of cellular processes, aiding in research related to cancer, immunology, and molecular biology.
