Used in biochemical research and diagnostic assays to catalyze the oxidative decarboxylation of 6-phosphogluconate to ribulose-5-phosphate, generating NADPH in the pentose phosphate pathway. The lyophilized form allows for stable storage and easy handling in enzyme activity studies, metabolic pathway analysis, and enzyme kinetics experiments. Commonly employed in coupled enzyme reactions for detecting coenzyme activity or measuring glucose-6-phosphate dehydrogenase levels. Suitable for in vitro applications requiring high enzyme purity and specific activity, particularly in studies related to cellular redox balance and nucleotide synthesis.
