Applications

Biotin-PEG11-Mal selectively reacts with sulfhydryl groups (at pH 6.5-7.5), facilitating the formation of thioether linkages. The hydrophilic PEG spacer enhances the aqueous solubility of molecules conjugated to the biotin compound while reducing steric hindrance during binding to avidin molecules.
