Biotin-PEG(3)-SS-Py

 Biotin-PEG(3)-SS-Py/Biotin-PEG(3)-SS-pyridin combines the high affinity of biotin for avidin or streptavidin, the flexibility and steric distance provided by the PEG linker, the reversible covalent interactions through the disulfide bond, and the selective reactivity of the pyridyl group. It is commonly used for biotinylation of biomolecules, protein purification, reversible protein modification, and controlled release applications in biological and biomedical research.
