Dichlorotriazine-based multivalent probe for selective affinity labeling of carbohydrate-binding proteins

Abstract

A new series of multivalent gold nanoparticle probes bearing different electrophilic groups were synthesized and their affinity labeling reactivities were evaluated. The dichlorotriazine group was identified as a useful protein-reactive label, allowing selective capture of a target protein at nanomolar probe concentrations.
