LC–MS Lipidomics
Typical lipidomics methods incorporate a liquid−liquid extraction with LC−MS quantitation; however, the classic sample extraction methods are not high-throughput and do not perform well at extracting the full range of lipids...

PURPOSE: To develop a sensitive analytical method to quantify gemcitabine (2',2'-difluorodeoxycytidine, dFdC) and its metabolites 2',2'-difluorodeoxyuridine (dFdU) and 2',2'-difluorodeoxycytidine-5'-triphosphate (dFdCTP)...
A comparison of murine epidermal Langerhans cells with spleen dendritic cells
To establish if epidermal Langerhans cells (LC) are related to spleen dendritic cells, we have considered the morphology, phenotype, and function of the 2 cell types in culture. Cultured LC could be partially enriched (up to...
