What is the principle of the "direct" or "homogeneous" HDL cholesterol automated method, which requires no intervention by the laboratorian? The direct HDL method. a. b. c. Quantifies only the cholesterol in HDL, whereas the precipitation HDL method quantifies the entire lipoprotein Utilizes polymers and detergents that make the HDL cholesterol soluble while keeping the other lipoproteins insoluble Uses a nonenzymatic method to Both the direct and the heparin sulfate manganese chloride precipitation methods measure HDL cholesterol. The direct or homogeneous method for HDL cholesterol uses a mixture of polyanions and polymers that bind to LDL and VLDL and chylomicrons, causing them to become stabilized. M measure cholesterol, whereas the The polyanions neutralize ionic other methods use enzymes to charges on the surface of the measure cholesterol lipoproteins, and this enhances their d. Uses a column chromatography binding to the polymer. When a step to separate HDL from the other detergent is added, HDL goes into ER lipoproteins, whereas the other solution, whereas the other lipoproteins methods use a precipitation step remain attached to the polymer/polyanion complexes. The HDL cholesterol then reacts with added cholesterol enzyme reagents while the other lipoproteins remain inactive. The reagents, polymer/polyanions, and detergent can be added to the AT specimen in an automated way without the need for any manual pretreatment step. Furthermore, the direct HDL cholesterol procedure has the capacity for better precision than the manual precipitation methods. Both the adaptability to automated W installments and the better precision make the direct method a preferred choice for quantifying HDL cholesterol. 103.What is the sedimentation a. Very-low-density lipoproteins A double nomenclature exists for the nomenclature associated with (VLDLs) five principal lipoprotein fractions. The alpha-lipoprotein? b. High-density lipoproteins (HDLs) nomenclature is such that the various c. Low-density lipoproteins (LDLs) fractions have been named on the d. Chylomicron basis of both the electrophoretic mobilities and the ultracentrifugal sedimentation rates. The chylomicrons are known as chylomicrons by both methods. The chylomicrons are the least dense fraction, exhibiting a solvent density for isolation of less than 0.95 g/mL, and have the slowest electrophoretic mobility. The HDLs, also known as the alpha-lipoproteins, have the greatest density of 1.063-1.210 g/mL and move the fastest electrophoretically toward the anode. The VLDLs, also known as the prebeta-lipoproteins, move slightly slower electrophoretically than the alpha fraction. The VLDLs have a density of 0.95-1.006 g/mL. The IDLs, intermediate-density lipoproteins, have a density of 1.006-1.019 g/mL and migrate as a broad band between beta- and prebeta-lipoproteins. The LDLs, also known as the beta-lipoproteins, have an electrophoretic mobility that is slightly slower than that of the IDL fraction. The LDLs have an intermediate density of 1.019-1.063 g/mL, which is between the IDLs and the HDLs. To summarize the electrophoretic mobilities, the alpha-lipoprotein fraction migrates the farthest toward the anode from the K origin, followed in order of decreasing mobility by the prebeta-lipoprotein, broad band between beta and prebeta-lipoprotein, beta-lipoprotein, and chylomicron fractions.
