WebThe Bligh and Dyer method is a well-known method used for lipid extraction. In terms of the Folch method of achieving operating ratios, it is very similar to the acetone/ether/water ratio, which differs most from the solvent to the solvent. To remove lipids from cell suspension, a chloroform and methanol (1:2) mixture is used. Webchloroform: [noun] a colorless volatile heavy toxic liquid CHCl3 with an ether odor used especially as a solvent.
