Biotin-PEG3-acid is a water-soluble linker featuring a triethylene glycol spacer that connects biotin to a terminal carboxylic acid. This structure enables efficient conjugation to amine-functionalized biomolecules via standard coupling chemistries. The PEG3 moiety enhances solubility and reduces non-specific binding, while the biotin group provides high-affinity recognition for streptavidin and avidin systems. Ideal for bioconjugation applications requiring both stability and ease of functionalization.
Biotin-PEG3-acid serves as a versatile bifunctional linker for bioconjugation, enabling site-specific labeling via its terminal carboxylic acid and high-affinity biotin moiety. The three-ethylene glycol spacer provides enhanced solubility and reduced steric hindrance, facilitating efficient conjugation to amines under standard coupling conditions. Its bench-stable structure supports reliable use in protein labeling, affinity purification, and diagnostic assay development.
