in our previously described miniaturized agar system the main lipoprotein-density-classes from human plasma , namely very low density lipoproteins ( vldl ) , intermediate density lipoproteins ( idl ) , low density lipoproteins ( ldl ) , high density lipoproteins2 ( hdl2 ) and hdl3 and a mixture of all the five lipoproteins were added in rising concentrations ( from 1/10 to normal human plasma concentration ) to serum-free medium containing delipidated and deionized bovine serum albumin ( bsa ) , iron saturated transferrin and erythropoietin .
