โฆ Synopsis
The useful application of high-pressure liquid chromatography in biochemical research with adenine nucleotide analogues is demonstrated by using a glass-walled separating column at inlet pressures between 100 and 200 atm. Three different aspects are highlighted :
(1) purity control of the adenine nucleotide analogues;
(2) direct reaction monitoring by high-pressure liquid chromatography;
(3) high-pressure liquid chromatography data and mononucleotide conformation.

A high-performance liquid chromatographic method was developed for the determination of plasma purine nucleoside phosphorylase activity. In this method, the reaction mixture consisted of \(15 \mu\) l of plasma and \(285 \mu \mathrm{l}\) of \(50 \mathrm{mM}\) phosphate buffer ( \(\mathrm{pH} 7.4\) )
Nucleotides, nucleosides, and purine bases were extracted from human endomyocardial biopsies, freeze-clamped rat hearts, and porcine coronary sinus plasma. Perchloric acid extracts were neutralized with Freon-trioctylamine and analyzed at 250 nm by reverse-phase ion-pairing high-performance liquid c
