Introduction
Coenzyme A (CoA) is an essential metabolic cofactor synthesized from cysteine, pantothenate, and ATP. It is involved in many important biological activities including the synthesis and oxidation of fatty acids, pyruvate oxidation in the citric acid cycle and many others. One of CoA’s most crucial roles is the carrying and transferring of acyl groups. CoA levels can be altered during starvation, and in conditions such as cancer, diabetes, and alcoholism.
Coenzyme A Assay Kit provides a simple, reproducible, and sensitive tool of measuring Coenzyme A concentration in cell lysates, plasma, serum and other biological liquid samples. This assay employs a coupled enzymatic reaction system that combines multiple steps. Initially, CoA is converted to acyl-CoA which is oxidized to enoyl-CoA and hydrogen peroxide (H2O2). Peroxidase then catalyzes the reaction of hydrogen peroxide with the Colorimetric Probe to form a pink colored product. The optical density measured at 570nm is directly proportional to the concentration of Coenzyme A present in the sample.
