This video demonstrates lipid isolation from human neutrophils by a biphasic solvent system using methanol and chloroform.

Protocol

1. Lipid Isolation and Analysis of Human Blood-derived Neutrophils Take neutrophils and place them on ice. On the ice, pipette the neutrophils (present in methanol and chloroform solution) to a 15 mL screw-cap glass tube with a polytetrafluoroethylene (PTFE) seal and homogenize them by shaking for 1 min. Use glass tubes to prevent the lipids from binding to plastic surfaces. Use PTFE caps to prevent contamination from rubber/plastic. Add 2 mL of methanol followed 1 min lat…
