Dear colleagues, We are pleased to announce the publication of the Marion Island Marine Mammal Programme (MIMMP's) latest paper: “What’s in a whisker? High-throughput analysis of twenty-eight C19 and C21 steroids in mammalian whiskers by ultra-performance convergence chromatography-tandem mass spectrometry”.
Herein, we developed a novel method to analyze multiple steroids deposited chronologically along the length of seal whiskers. The manuscript describes an accurate quantification method for multiple steroids, measured in a single chromatography step which reduces the cost and time associated with the analyses. The advance of this method can contribute to our understanding of the impact of stress associated with environmental/climate changes that affect the health and survival of organisms, as well as to delineate the reproductive cycles of free-living mammals with cryptic life stages. I trust that the readership of this mailing list will find the manuscript of interest. https://www.sciencedirect.com/science/article/abs/pii/S1570023219316642?fbclid=IwAR0_9tajNPrR9JlBcM_62k1TW6_qp5eIQhv3nVaDfHpF1HPvzBPwPJ73NL4 https://www.researchgate.net/publication/339227340_What's_in_a_whisker_High-throughput_analysis_of_twenty-eight_C19_and_C21_steroids_in_mammalian_whiskers_by_ultra-performance_convergence_chromatography-tandem_mass_spectrometry Sincerely, Nico Lubcker PhD.
