NHS PEG alkyne, Mp 3000 - 100mg

NHS-PEG-Alkyne (Mw 3000) is a heterobifunctional polyethylene glycol (PEG) linker containing a succinimidyl ester (NHS) on one end and an alkyne group on the other. This reagent enables efficient bioconjugation between amine-containing molecules (such as proteins or peptides) and azide-functionalized compounds via click chemistry (CuAAC). The PEG spacer (molecular weight ~3000 Da) enhances water solubility, reduces steric hindrance, and improves biocompatibility in crosslinking and labeling reactions.
