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