METHODS AND KITS FOR THE DETERMINATION OF THE PRESENCE AND QUANTITY OF VITAMIN D ANALOGS IN SAMPLES
摘要
Embodiments of the present invention are directed to methods and kits for determining the presence or absence, and the amount if present, of vitamin D analogs in samples. One embodiment of the present method for detecting the presence or absence of vitamin D analogs in a sample comprises the steps of adding an effective amount of a multiple charge cationic agent to the sample to form a cationic treated sample. The effective amount of a multiple charge cationic agent enhances the signal from vitamin D analogs upon analysis by mass spectroscopy.
