Amino-PEG24-alcohol is widely used in bioconjugation and drug delivery systems due to its water solubility and biocompatibility. It serves as a linker molecule, connecting drugs, peptides, or proteins to enhance their stability and solubility. In therapeutic applications, it is utilized to modify antibodies, proteins, or nanoparticles, improving their pharmacokinetics and reducing immunogenicity. Additionally, it is employed in the development of targeted drug delivery systems, ensuring precise delivery of therapeutic agents to specific cells or tissues. Its long PEG chain also helps in reducing aggregation and increasing circulation time in the body. Furthermore, it is used in diagnostic applications for labeling and imaging purposes, enhancing the detection of biomolecules.
