DETERMINATION OF ADENOSINE PHOSPHATES IN WHOLE-BLOOD BY CAPILLARY ZONE ELECTROPHORESIS

The pool of chemical energy in an organism represented by high-energy compounds can be assessed by means of adenosine triphosphate (ATP) det ermination in whole blood and tissues. The elegant manner for the dete rmination of adenosine phosphates (ATP, ADP, AMP) in a single assay is offered by the technique of capillary zone electrophoresis. For this purpose, the BioFocus 3000 Capillary Electrophoresis System (BIO-RAD L aboratories, Inc., Hercules, CA, USA) was used. For the construction o f calibration curves, pure preparations of ATP, ADP and AMP were analy zed. The method was used for adenosine phosphates determination in the umbilical blood samples from physiological and immature newborns. Cap illary zone electrophoresis enables a specific and simultaneous determ ination of adenosine phosphates and, thus, monitoring of unusual metab olic situations.
