Nucleoside hydrolase immobilized on magnetic particles as a tool for onflow screening and characterization of inhibitors.

Nucleoside Hydrolases (NH) are considered a target for the development of new antiprotozoal agents. The development of new and automated screening assays for the identification of NH inhibitors can accelerate the first stages of the drug discovery process. In this work, NH from Leishmania donovani (LdNH) was covalently immobilized onto magnetic particles (LdNH-MPs) and trapped by magnets into a TFE tube to yield an immobilized enzyme reactor (IMER).
