Abstract
Official abstract text for this publication.
Provided are methods of detecting the presence or amount of a dihydroxyvitamin D metabolite in a sample using mass spectrometry. The methods generally comprise associating an amine with a dihydroxyvitamin D metabolite in a sample, ionizing the adduct, and detecting the amount of the ion to determine the presence or amount of the vitamin D metabolite in the sample.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for quantifying the amount of a dihydroxyvitamin D metabolite in a sample, comprising the steps of: (a) combining a first sample comprising an amount of dihydroxyvitamin D metabolite with an amine selected from the group consisting of glycine, alanine, serine, arginine, thyroxine, triiodothyronine, diiodothyronine and iodothyronine, thereby forming a second sample comprising non-covalent adducts comprising the dihydroxyvitamin D metabolite and the…
