Bis-PEG2-NHS ester enables efficient, dual-functional conjugation in aqueous media. This bifunctional reagent features two NHS ester groups separated by a short PEG2 spacer, promoting stable amide bond formation with primary amines. The hydrophilic PEG linkage enhances solubility and reduces non-specific binding, making it ideal for protein labeling, peptide coupling, and bioconjugate synthesis under physiological conditions.
Bis-PEG2-NHS ester serves as a bifunctional crosslinking agent enabling efficient conjugation of biomolecules and surface-bound amines. Its two PEG2 spacers provide enhanced solubility and reduced steric hindrance, while the NHS ester groups react selectively with primary amines under physiological conditions. Ideal for antibody-drug conjugation and bioconjugation workflows, it offers excellent stability in aqueous buffers and facilitates straightforward purification due to minimal byproduct formation.
