2,3;5,6-Di-O-isopropylidene-1-O-(2-phenylacetyl)-α-d-mannofuranose

Acta Crystallographica Section E, 2010
The title compound, C20H26O7, was prepared by esterification of 2,3;5,6-di-O-isopropylidene-α-d-mannofuranose with phenylacetic acid under standard DCC/DMAP (DCC = dicyclohexylcarbodiimide and DMAP = 4-dimethylaminopyridine) conditions.

Isolation of mycoplasma membranes by dicyclohexylcarbodiimide-induced lysis [PDF]

Journal of Bacteriology, 1982
A simple procedure was devised to prepared membranes from Mycoplasma gallisepticum cells. The cells were lysed in an isosmotic NaCl solution by dicyclohexylcarbodiimide, which blocks ATPase activity and interferes with the regulation of cell volume. The procedure can be used to isolate membranes of other osmotically resistant mycoplasmas.

Reconstitution of Mitochondrial Oligomycin and Dicyclohexylcarbodiimide‐Sensitive ATPase [PDF]

European Journal of Biochemistry, 1980
1. Oligomycin and dicyclohexylcarbodiimide‐sensitive ATPase was isolated from beef‐heart mitochondria and treated with 3.5 M NaBr in order to remove F1. The residue, called F0, was found to consist of seven components. Five of these are stained by Coomassie blue after dodecyl‐sulfate‐polyacrylamide‐gel electrophoresis.
