METHODS FOR DETECTING OR QUANTIFYING CTP AND CTP SYNTHASE ACTIVITY

摘要

The present invention relates to a method for detecting or quantifying CTP in a cell sample comprising at least two nucleotide triphosphates by cationic ion pairing chromatography coupled to mass spectrometry, to a method for detecting or quantifying CTP synthase activity based on the method for detecting or quantifying CTP, and to their use in methods for screening potential immunosuppressive or anti-cancer compounds and in methods for determining the appropriate dose of an immunosuppressive or anti-cancer compound inhibiting CTP synthase activity for a treated subject.
