Description

Propargyl-PEG3-NHS ester enables efficient conjugation in bioorthogonal labeling workflows. This bifunctional reagent combines a reactive NHS ester with a terminal alkyne, facilitating rapid, selective coupling to amine-containing biomolecules under physiological conditions. The PEG3 spacer provides enhanced solubility and reduced steric interference, while the propargyl group supports subsequent click chemistry applications such as copper-catalyzed or strain-promoted cycloadditions.

Application

Propargyl-PEG3-NHS ester enables efficient conjugation of biomolecules under physiological conditions, leveraging the orthogonal reactivity of the propargyl group with azides via copper-free click chemistry. The PEG3 spacer provides enhanced solubility and reduced steric hindrance, while the NHS ester facilitates rapid amine coupling. This reagent serves as a versatile bifunctional linker for protein labeling, probe synthesis, and bioconjugation workflows requiring site-specific modification and stability in aqueous environments.
