Propargyl-PEG2-NHS ester enables site-specific conjugation in aqueous media, combining a reactive NHS group with a terminal alkyne for bioorthogonal labeling. This bifunctional linker features a short PEG spacer that enhances solubility and reduces steric hindrance, facilitating efficient coupling to primary amines on proteins, antibodies, or peptides while preserving functional integrity.
Propargyl-PEG2-NHS ester serves as a versatile bifunctional linker for conjugation chemistry, enabling efficient coupling of biomolecules to surfaces or solid supports via its reactive NHS ester group. The propargyl moiety provides a bioorthogonal handle for copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating site-specific labeling and assembly of functionalized constructs. Its PEG2 spacer enhances solubility and reduces non-specific binding, while the reagent exhibits excellent bench stability and ease of purification—ideal for applications in probe synthesis, protein modification, and materials science.
