[HDL phospholipids determination after precipitation by concanavalin A (author's transl)].

The interest in the HDL phospholipids determination for cardiovascular disease investigations leads us to study its determination by an easy and accurate procedure: precipitation of lipoproteins bound to apo B with concanavalin A and determination of phospholipids in the supernatant by an enzymatic procedure. From our preliminary study, we refuse the heparin Mn Cl2 precipitation. Our method is compared with phosphotungstate Mg Cl2 precipitation procedure.
