Simple liquid chromatography-electrospray ionization mass spectrometry method for the routine determination of salmon calcitonin in serum.

A simple liquid chromatography-electrospray ionization mass spectrometry (LC-ESI-MS) method was developed for the quantification of salmon calcitonin (sCT) in serum. Serum samples from rats and dogs were deproteinized and freeze-dried. The residue was then reconstituted with 57% acetonitrile in water containing 0.
