In the ACE γ-GT Reagent assay, γ-GT in serum or heparin plasma catalyzes the transfer of the γ-glutamyl group from L-γ-glutamyl-3-carboxy-4-nitroanilide to glycylglycine in the reagent. The product, 5-amino-2-nitrobenzoate, absorbs strongly at 408 nm. The rate of increase in absorbance, monitored bichromatically at 408 nm/486 nm, is directly proportional to the γ-GT activity in the sample. In the ACE Lipase Reagent Assay, lipase in serum or heparin plasma acts on a natural substrate, 1,2-diglyceride, to liberate 2-monoglyceride. This is hydrolyzed by monoglyceride lipase (a highly specific enzyme for monoglyceride) into glycerol and free fatty acid. Glycerol kinase acts on glycerol to form glycerol-3-phosphate, which is in turn acted on by glycerol-3-phosphate oxidase to generate hydrogen peroxide. Peroxidase converts the hydrogen peroxide, 4-Aminoantipyrine and TOOS (N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine) into a quinine dye. The rate of formation of the dye, determined bichromatically at an absorbance of 573 nm/692 nm, is proportional to the lipase activity in the sample. The ACE T4 Assay is a homogeneous enzyme immunoassay using ready-to-use liquid ACE T4 Reagent. The assay uses 8-anilino-1-naphthalene sulfonic acid (ANS) to dissociate thyroxine from the plasma binding proteins. Using specific antibodies to thyroxine, this assay is based on the competition of glucose-6-phosphate dehydrogenase (G6PD) labeled thyroxine and the dissociated thyroxine in the sample for a fixed amount of specific antibody binding sites. In the absence of thyroxine from the sample, the thyroxine labeled G6PD in the second reagent is bound by the specific antibody in the first reagent, inhibiting the enzyme's activity. The enzyme G6PD catalyzes the oxidation of glucose-6-phosphate (G6P) with nicotinamide adenine dinucleotide (NADT) to form 6-phosphogluconate and reduced nicotinamide adenine dinucleotide (NADH). NADH strongly absorbs at 340 nm whereas NAD does not. The rate of conversion, determined by measuring the increase in absorbance bichromatically at 340 nm/505 nm during a fixed time interval, is directly proportional to the amount of thyroxine in the sample. The concentration of thyroxine is determined automatically by the ACE Clinical Chemistry Systems using a logarithmic calibration curve established with calibrators, which are provided separately.

For in vitro diagnostic use only. The ACE Serum Iron Reagent is intended for the quantitative determination of iron concentration in serum using the ACE Axcel Clinical Chemistry System. Iron (non-heme) measurements are used in the diagnosis and treatment of diseases such as iron deficiency anemia, hemochromatosis (a disease associated with widespread deposit in the tissues of two iron-containing pigments, hemosiderin and hemofuscin, and characterized by pigmentation of the skin), and chronic renal disease. This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only. The ACE Lipase Reagent is intended for the quantitative determination of lipase activity in serum using the ACE Axcel Clinical Chemistry System. Lipase measurements are used in diagnosis and treatment of diseases of the pancreas such as acute pancreatitis and obstruction of the pancreatic duct. This test is intended for use in clinical laboratories or physician office laboratories. For in vitro diagnostic use only.

The ACE Axcel Clinical Chemistry System consists of two major components, the chemistry instrument and an integrated Panel PC. The instrument accepts the physical patient samples, performs the appropriate optical or potentiometric measurements on those samples and communicates that data to an integral Panel PC. The Panel PC uses keyboard or touch screen input to manually enter a variety of data, control and accept data from the instrument, manage and maintain system information and generate reports relative to patient status and instrument performance. The Panel PC also allows remote download of patient requisitions and upload of patient results via a standard interface. In the ACE Direct Total Iron-Binding Capacity (TIBC) Reagent assay, Direct TIBC Color Reagent, an acidic buffer containing an iron-binding dye and ferric chloride, is added to the serum sample. The low pH of Direct TIBC Color Reagent releases iron from transferrin. The iron then forms a colored complex with the dye. The colored complex at the end of the first step represents both the serum iron and excess iron already present in Direct TIBC Color Reagent. Direct TIBC Buffer, a neutral buffer, is then added, shifting the pH and resulting in a large increase in the affinity of transferrin for iron. The serum transferrin rapidly binds the iron by abstracting it from the dye-iron complex. The observed decrease in absorbance of the colored dye-iron complex is directly proportional to the total iron-binding capacity of the serum sample. The absorbance is measured at 647 nm. In the ACE Serum Iron Reagent assay, transferrin-bound iron in serum is released at an acidic pH and reduced from ferric to ferrous ions. These ions react with ferrozine to form a violet colored complex, which is measured bichromatically at 554 nm/692 nm. The intensity of color produced is directly proportional to the serum iron concentration. In the ACE Lipase Reagent Assay, serum lipase acts on a natural substrate, 1,2-diglyceride, to liberate 2-monoglyceride. This is hydrolyzed by monoglyceride lipase (a highly specific enzyme for monoglyceride) into glycerol and free fatty acid. Glycerol kinase acts on glycerol to form glycerol-3-phosphate, which is in turn acted on by glycerol-3-phosphate oxidase to generate hydrogen peroxide. Peroxidase converts the hydrogen peroxide, 4-Aminoantipyrine and TOOS (N-ethyl-N-(2-hydroxy-3-sulfopropyl)-m-toluidine) into a quinine dye. The rate of formation of the dye, determined bichromatically at an absorbance of 573 nm/692 nm, is proportional to the lipase activity in the sample.
