The potential importance of the methylation cycle during embryonic development necessitates the establishment of methodology to detect alterations in the relative abundance of s-adenosylmethionine (SAM) and s-adenosylhomocysteine (SAH) in an embryonic experimental system. We have developed a precise and sensitive method for measurement of SAM and SAH based on liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) in single neurulation-stage mouse embryos. Use of a penta-fluorinated high-performance liquid chromatography (HPLC) stationary phase gave enhanced sensitivity due to optimal ionisation in organic mobile phase and increased retention time compared to standard reversed-phase separation. Calibration curves suitable for the analysis of neurulation-stage mouse embryos (SAM 0.02-25.0microM, SAH 0.01-10.0microM) were linear (r(2)>0.997) with limits of detection for SAM and SAH of 10 and 2.5nmol/L, respectively.
