Propargyl-PEG2-amine features a reactive alkyne handle flanked by two ethylene glycol units, enabling efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC). This bifunctional linker combines excellent water solubility with stable conjugation chemistry, ideal for bioconjugation and surface functionalization in aqueous environments.
Propargyl-PEG2-amine serves as a versatile bifunctional linker for conjugation chemistries, enabling efficient CuAAC reactions via its terminal alkyne group while providing a primary amine for orthogonal coupling. Its short PEG spacer enhances solubility and reduces steric hindrance, facilitating reliable bioconjugation in peptide, oligonucleotide, and antibody labeling workflows. The compound exhibits excellent bench stability and is compatible with standard purification methods.
