The phospholipase A2 enzyme (LM-LPA2-I) was purified
by two chromatographies steps; a gel filtration on a
Sephacryl S-200HR followed by a reverse-phase C2/C18 using
FPLC apparatus as previously described (Fuly et al., 1997).
Lipids (LPC as well as fatty acids) were dissolved in small
volumes of chloroform, dried to a thin film under a gentle
nitrogen flow and vacuum pumped to remove the organic
solvent. After, dried lipid was suspended in 150 mM NaCl,
extensively vortexed and then ultrasonically dispersed in
a bath sonicator for 5 min at room temperature. Then, lipids
were kept at 4 C until experiments.
