Biotin-PEG-COOH (Biotin-PEG-Acid) offers precise bioconjugation capabilities and enables the functionalization of surfaces and biomolecules. Its integration into diagnostic assays, drug delivery systems, and biomedical applications enhances the specificity, sensitivity, and versatility of biological studies and technological developments. Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble vitamin that binds specifically and tightly to streptavidin and avidin proteins. PEG is a biocompatible, hydrophilic polymer chain. It is often used in bioconjugation to increase solubility, reduce non-specific interactions, and improve the pharmacokinetic profile of biomolecules. The carboxylic acid group at the end of the PEG chain provides a reactive site for conjugation with primary amines (-NH2) or other functional groups via amide bond formation.
