The present paper describes a simple HPLC method designed for measuring high-energy phosphate (HEP) compounds in a single run and inorganic phosphate (Pi) in an other short run under the same HPLC conditions. Inorganic phosphate was estimated by using thymidine phosphorylase (EC 2.4.2.4) which catalyzes a reaction involving inorganic phosphate to produce 2-deoxyribose 1-phosphate and thymine.

Abstract

The present paper describes a simple HPLC method designed for measuring high-energy phosphate (HEP) compounds in a single run and inorganic phosphate (Pi) in an other short run under the same HPLC conditions. Inorganic phosphate was estimated by using thymidine phosphorylase (EC 2.4.2.4) which catalyzes a reaction involving inorganic phosphate to produce 2-deoxyribose 1-phosphate and thymine. The thymine/Pi stoichiometry was 1. The method provides a reproducible instrument for evaluating myocardial high-energy metabolism under physiological and pathological conditions.
