Mal-EGGGG-PEG8-amide-bis(deoxyglucitol)(CAT: I040759) is a multifunctional linker molecule designed for advanced bioconjugation and targeted delivery applications. It contains a maleimide (Mal) group for selective thiol conjugation, enabling site-specific attachment to proteins or peptides. The EGGGG peptide spacer and PEG8 chain enhance flexibility, solubility, and reduce immunogenicity, improving the pharmacokinetic profile of conjugates. The bis(deoxyglucitol) moieties, derived from sugar structures, can aid in cellular targeting or metabolic labeling. This versatile compound is ideal for constructing antibody-drug conjugates (ADCs), glycan-based therapeutics, and other precision delivery systems in biomedical and pharmaceutical research.
