A mechanism-based affinity-labeling agent for possible use in isolating N-acetylglucosaminidase

We have prepared several mechanism-based affinity-labeling agents for possible use in isolating N-acetylglucosaminidase, in which an N-acetylglucosamine is linked to an o-monofluoro- or difluoro-methyl phenoxy glycoside with or without a cleavable disulfide group in the tether to biotin.
