This article describes the development and validation of a sensitive and robust method for the determination of neurosteroids in sea lamprey, an ancestral animal in vertebrate evolution. Chemical derivatization was used to enhance the detection of neurosteroids containing ketone function by ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Iminooxy derivatives of...
A rapid liquid chromatography–tandem mass spectrometry (LC–MS/MS) method was developed and validated for simultaneous quantification of three monoamine neurotransmitters (NTs) and melatonin in sea lamprey brain tissues. Separation was performed on a reversed-phase column with mobile phases of 1mM perfluoroheptanoic acid (PFHA) water solution/acetonitrile and mass spectra were acquired in positive...
