This direct method for quantifying cholesterol in low-density lipoproteins (LDL) is based on modified polyvinyl sulfonic acid (PVS) and polyethylene glycol methyl ether (PEGME) associated with the classic precipitation method in optimized ratios of PVS/PEGME and selected detergents. LDL

The method is based on the segmentation of the specific chromogenic substrate 1,2-O-dilaurylrac-glycero-3-glutaric- (6'methyl-resorufin)-ester emulsified in stabilising micro-particles. In the presence of specific pancreatic lipase activators such as colipase, calcium ions and bile acids, the substrate is transformed into 1,2-O-dilauryl-rac-glycerol and glutaric acid-6′-methylresorufinester which spontaneously decomposes to glutaric acid and methylresorufin. The intensity of the colour formed is proportional to the concentration of lipase in the sample.

The method is based on the specific binding of calmagite, a metallochromic indicator, to magnesium at alkaline pH with a consequent shift of the absorption spectrum of the complex. The intensity of the chromophore formed is proportional to the concentration of magnesium present in the sample.
