Description

Biotin-PEG4-PFP ester provides versatility in bioconjugation strategies. It can be used to attach biotin to various biomolecules (proteins, peptides, antibodies) for applications in targeted drug delivery, imaging agents, or biosensors. Biotin (Vitamin B7) is a small molecule known for its high affinity for streptavidin and avidin proteins, which is crucial for molecular tagging and detection. PEG enhances solubility, reduces aggregation, and improves the pharmacokinetic properties of conjugated biomolecules. PFP (pentafluorophenyl) ester is a reactive moiety that is commonly used in bioconjugation chemistry. It reacts with primary amines (-NH2) of proteins or peptides to form stable amide bonds. The resulting linkage is stable under physiological conditions, providing a covalent attachment of biotin to the biomolecule.
