Study TitleMetabolomics Analysis of Thermally Challenged Mayfly Larvae (GCMS analysis)
Study TypeMetabolomic analysis of mayflies
Study SummaryThe purpose of this study was to examine the metabolic profiles of mayfly (Centroptilum triangulifer) larvae subjected to thermal challenge. This species is unusual in terms of its ease of culture, and its suitability as a laboratory test organism. Our purpose here was to examine how an environmentally realistic thermal challenge affects the physiology of this organism. In this study, we obtained several types of insect species and we were able to show that GC-MS Metabolomics could be used to distinguish among the different types of larvae.

Sample Preparation:

Sampleprep ID:SP000038
Sampleprep Summary:Insect samples homogenized in 50% acetonitrile at a concentration of 50 mg/mL. Sample dried and aliquot taken for NMR. Sample returned and extract processed for GC/MS analysis. Samples were derivatized using 2 step derivatization method (methoximation with methoxy amine followed by TMS derivatization with MSTFA).
