Method for measuring polyamines in erythrocytes, diagnostic method and kit for measuring polyamines in erythrocytes

摘要

A method for measuring polyamines in erythrocytes in which a polyamine oxidase having a substrate specificity to spermine and spermidine or a polyamine oxidase having a substrate specificity to spermine only is used, an eluate in erythrocytes separated and purified from blood is reacted with these enzymes, and hydrogen peroxide formed is determined with a highly sensitive chromogen1 such as a diphenylamine-based chromogen. A method for measuring amounts of polyamines in erythrocytes easily with high precision. The method is effective for diagnosis of certain disease conditions or physiological conditions or the like.
