Project ID:PR000125
Project DOI:doi: 10.21228/M8DW2B
Project Title:Mammalian Suspension-Cultured Cellular Metabolomics Workflow
Project Type:Metabolomics, Lipidomics, Untargeted
Project Summary:A workflow was optimized for the sample preparation of a single suspension-cultured cell pellet for both metabolomics and lipidomics analysis. Jurkat T-lymphocyte cells were washed with various rinsing solutions and the lipids extracted using different lipid extraction protocols to allow for the most reproducible and quantitative method.
