Biotin-PEG-Biotin is a bifunctional reagent with biotin groups at both ends of a linear PEG chain. It can be used for crosslinking PEGylation by binding to two streptavidin or avidin molecules with high affinity and specificity. The biotin groups are conjugated to the PEG chain through stable amide linkers, making it ideal for creating stable, biocompatible complexes in various biomedical applications, including targeted drug delivery and diagnostic assays.
