N3-PEG2-Tos
Biochemical Assay Reagent
N3-PEG2-Tos is a bioconjugation reagent comprising a small polyethylene glycol (PEG) linker, equipped with an azide group and a tosylate leaving group. The tosylate moiety facilitates nucleophilic substitution reactions, while the azide serves as a versatile handle for click chemistry applications, enabling efficient coupling with terminal alkynes or strained cyclooctynes. This reagent is ideal for biochemical assays and applications in bioorthogonal labeling and peptide or protein conjugation.
