title: Determination of creatine phosphate levels in brain tissue by isocratic reverse-phase, ion-paired high-performance liquid chromatography.
abstract: The utilization of isocratic, reverse-phase, ion-paired high-performance liquid chromatography for analysis of creatine phosphate allows for rapid quantification of multiple samples. Cryogenic sample handling and the addition of ethylene glycol bis(beta-aminoethyl ether) N,N'-tetraacetic acid as a Ca2+ sequestering agent during perchloric acid extraction enhance maximal recovery of creatine phosphate from brain samples. Peak identification is supported by a complete enzymatic shift with a phosphocreatine kinase, hexokinase, and glucose-6-phosphate dehydrogenase system.
