A-25 Method for Measuring Polyamines in Erythrocytes
Measuring polyamines in blood instead of urine is easy and accurate: the existing method for measuring polyamine in urine requires pretreatment for hydrolysis.polyamine concentrations in urine do not always correlate directly to concentrations within the body. Improved simplicity: Some enzymatic methods use two types of amine oxidases derived from bacteria in two-step enzymatic reactions.

Title: Method for measuring polyamines in erythrocytes, diagnostic method and kit for measuring polyamines in erythrocytes
Usefulness: Method for measuring polyamines in erythrocytes, diagnostic method and kit for measuring polyamines in erythrocytes
Summary: The invention deals with a method for measuring polyamines in erythrocytes (blood). The method is useful for diagnosis of diseases (diagnosis of infections, cancer, cirrhosis, diabetes (type I), Alzheimer's disease, diagnosis for prognosis of organ excision or organ transplantation). (All claimed). The method is useful for measuring (I) in urine.
Novelty: Measuring polyamines in erythrocytes comprises reacting eluate of erythrocytes with polyamine oxidase having substrate specificity to spermine and spermidine and determining hydrogen peroxide formed with sensitive chromogen
