  • Title: Selection of enzyme sources for improved sensitivity in enzymatic determination of organophosphorus pesticides.
    Author: Udaya Bhaskar S, Nanda Kumar NV.
    Journal: J Assoc Off Anal Chem; 1982 Nov; 65(6):1297-8. PubMed ID: 7174570.
    Abstract:
    The Michaelis-Menten constant (Km) for cholinesterases from different liver sources, the inhibitor concentration for 50% inhibition (I50), and the lower limit of estimation were determined for 3 organophosphorus pesticides and their oxygen analogs. Maximum sensitivity in organophosphorus pesticide determinations can be achieved by choosing the enzyme source which has a higher Km value. An inverse relationship is suggested between Km and the lower limit of estimation.
