ACE® LDL-C Reagent is intended for use in the quantitative determination of low density lipoprotein cholesterol in human serum. ACE® LDL-C Reagent is intended for the quantitative determination of LDL cholesterol in serum using the ACE® clinical chemistry system. LDL-C Calibrator is intended for the calibration of the ACE® LDL-C Assay. LDL-C Controls are intended to monitor the performance of the ACE® LDL-C Assay. The measurement of LDL cholesterol is a factor in the pathogenesis of atherosclerosis and coronary artery disease.

The ACE® LDL-C Reagent contains two reagents. An aliquot of serum is added to the first reagent, which contains a unique detergent that selectively solubilizes the non LDL lipoproteins. Enzymes also present in the first reagent consume the cholesterol in a non color forming reaction. The second reagent contains another detergent that releases the remaining LDL lipoproteins. The enzyme reaction with LDL cholesterol, in the presence of a chromogenic coupler, produces color that is directly proportional to the amount of LDL cholesterol in the sample.

ACE T Uptake Reagent is used in the diagnosis and treatment of thyroid disorders. It is intended for the quantitative determination of unsaturated binding sites on the thyroid-binding proteins in serum using the ACE clinical chemistry analyzer.

The ACE T Uptake Regent contains two reagents, and Antibody/Substrate reagent and an Enzyme The assay uses a mixture of enzyme glucose-6-phosphate dehydrogenase Conjugate reagent. conjugated thyroxine (G6PD-T4) and a known amount of exogeneous T4 which is allowed to bind to the thyroxine-binding proteins in the sample. A sample with increased levels of unsaturated thyroxine-binding sites, the exogeneous T4 will bind leaving G6PD-T4 conjugate free. On addition of an anti-thyroxine antibody, the G6PD-T4 conjugate is bound by the antibody and the enzyme activity is inhibited. Conversely, a sample with decreased levels of unsaturated thyroxine-binding sites will leave most exogeneous T4 unbound. Upon addition of anti-T4 antibody, the unbound exogeneous T4 will inhibit the anti-T4 binding to G6PD-T4 conjugate and produce a high G6PD enzyme activity. This phenomenon creates a relationship between unsaturated thyroxine-binding sites concentration (T Uptake) and the enzyme activity. The enzyme G6PD activity is determined bichromatically on the ACE® at 340/505 nm by measuring its ability to convert NAD* to NADH.

This in vitro diagnostic product is intended for the quantitative determination of HDL cholesterol in human serum. Numerous studies have shown an inverse relationship between serum HDL cholesterol and the risk of coronary heart disease. HDL cholesterol also has an important role in the pathogenesis of atherosclerosis.

An aliquot of serum is added to the first reagent which contains a mixture of polymers and polyanions that bind to the surface of low-density lipoproteins (LDL), very low-density lipoproteins (VLDL) and chylomicrons. These complexed lipoproteins are stabilized, even in the presence of detergent, which is added as part of the second reagent, together with cholesterol enzymes. HDL particles are not stabilized by the polymers and polyanions and become solubilized by the detergent. As a result, only the HDL cholesterol is subject to measurement.
