Chloroform methanol extraction of lipids
WebThen, lipids were re-suspended in 40 µL of chloroform:methanol 1:1 (v/v) mixture and either stored at -20°C for subsequent analysis or immediately used. Phospholipid classes from the total lipid extract were separated by thin-layer chromatography (TLC) using glass plates of pre-coated 0.25 mm silica gel with fluorescent indicator UV254. WebTo remove lipids from cell suspension, a chloroform and methanol (1:2) mixture is used. The gravimetric method is still used for counting lipids, even though high-pressure …
