Application

3-epi-25-Hydroxyvitamin D3 abbreviated as 3-epi-25(OH)D3 is a metabolite of vitamin D3 produced in the liver. 3-epi-25(OH)D3 is used as a biomarker to determine the status of vitamin D in the body. It can be also employed as an analytical standard for the quantification of 3-epi-25(OH)D3 molecules in human serum using the LC-MS/MS method.

The metabolic role and health implications of the various vitamin D isoforms are of current clinical interest. Therefore, it is important to have an analytical method that will resolve all of the known isoforms with necessary sensitivity and specificity

This application shows an Ascentis Express F5 provided rapid resolution of the isobaric vitamin D metabolites. MS detection provides the necessary secondary resolution.
