Acid-PEG4-alpha-D-mannose is a versatile sugar PEG linker featuring a reactive carboxylic acid and an α-D-mannose moiety. The acid enables amide bond formation for selective conjugation to proteins, peptides, or other biomolecules. The PEG4 arm improves aqueous solubility and flexibility while minimizing steric hindrance. This compound targets mannose-binding receptors, making it ideal for bioconjugation, targeted drug delivery, immunology studies, and diagnostic applications where precise receptor-mediated interactions are required.
