Biotin-PEG-Mal

Biotin-PEGn-Maleimide is primarily used for site-specific bioconjugation to thiol groups (-SH) in proteins, peptides, and other biomolecules, enabling applications in detection, purification, and targeting. Its key benefits include the water-soluble PEG spacer which reduces steric hindrance and increases stability, while the maleimide group ensures efficient and stable thiol coupling.
