A procedure is described whereby a highly enriched plasma membrane fraction was isolated from Trypanosoma brucei by the technique of preparative free-flow electrophoresis. The purity of the plasma membrane fraction was monitored by electron microscopy and by marker enzymology, and is compared to those obtained by previous methods. Proteins associated with plasma membrane fraction were analyzed by SDS-PAGE and phase separated in Triton X-114.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
