Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Ether-derived alkanes from sedimentary organic matter

, 1990
Glycerol ether lipids have been detected in the bitumen of DSDP sediments from Sites 467, 440B and 380 and from the Green River Shale. The alkyl side groups of these ethers were determined by conversion into deuteroalkanes.
