Sample Preparation:

Sampleprep ID:	SP001988
Sampleprep Summary:	Total lipids from OMV and TM were extracted based on the Bligh and Dyer chloroform:methanol method (1). Briefly, 2 volumes of methanol, 1 volume of chloroform, and 0.8 volumes of Milli-Q water were added to 1 volume of PBS-resuspended OMV or TM fractions into solvent-resistant glass tubes. Contents were mixed for 1 min by vortexing and 1 volume of chloroform was added to the mixture. Contents were mixed for another minute and tubes were centrifuged for 5 min at 4000 rpm. After centrifugation, bottom phase (organic) was recovered using a glass Pasteur pipette and stored in solvent-sealed vials at -80°C until lipid analysis by LC-MS. References: 1. Bligh EG, Dyer WJ. A rapid method of total lipid extraction and purification. Can J Biochem Physiol. 1959;37(8):911-7.
