Method of measuring the activity of a kynurenine aminotransferase and kit for performing such method

摘要

The present invention relates to a method of measuring the activity of a kynurenine-converting enzyme and/or a kynurenic-acid-, anthranilic-acid- and/or 3-hydroxykynurenine-producing enzyme, the method comprising the step of measuring the activity in the presence of an interfering sample, preferably selected from a CSF (cerebrospinal fluid) or serum, and detecting the conversion of kynurenine and/or kynurenic acid and/or anthranilic acid and/or 3-hydroxykynurenine.
