Used in biomedical research to quantify levels of human erythrocyte transketolase (ETK) in blood samples, aiding in the assessment of thiamine (vitamin B1) status. Particularly valuable in studies related to nutritional deficiencies, metabolic disorders, and conditions such as beriberi or Wernicke-Korsakoff syndrome. The kit enables high-throughput analysis in clinical and research laboratories, supporting investigations into glucose metabolism and erythrocyte enzyme activity.
