System reagent for the quantitative determination of Cholinesterase activity (E.C. 3.1.1.8) in human serum and plasma on Beckman Coulter Synchron CX® Pro System(s), Synchron LX® Pro System(s) and UniCel® DxC 600/800 System(s). Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders (e.g., insecticide poisoning and succinylcholine poisoning).

System reagent for the quantitative determination of Cholinesterase activity (E.C. 3.1.1.8) in human serum and plasma on Beckman Coulter Synchron CX® Pro System(s), Synchron LX® Pro System(s) and UniCel® DxC 600/800 System(s). A cholinesterase test system is a device intended to measure cholinesterase (an enzyme that catalyzes the hydrolysis of acetylcholine to choline) in human specimens. There are two principal types of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes (red blood cells) but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is not present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders (e.g., insecticide poisoning and succinylcholine poisoning). The method is based on the recommendations of the German Society for Clinical Chemisty (Deutsche Gesellschaft für Klinische Chemie, DGKCh). Cholinesterase catalyses the hydrolysis of butyrytthiocholine to butyrate and thiocholine. Thiocholine reduces yellow hexacyanoferrate (III) to colorless hexacvanoferrate (II). The decrease in absorbance at 410 nm is directly proportional to the cholinesterase activity in the sample.

The Cholinesterase Gen.2 Test System is an in vitro test for the quantitative determination of the catalytic activity of cholinesterase (EC 3.1.1.8; acylcholine acylhydrolase) in serum and plasma. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders.

The Cholinesterase Gen.2 Test System is an in vitro test for the quantitative determination of the catalytic activity of cholinesterase in serum and plasma. The test is based on the butyrylthiocholine method. Cholinesterase catalyzes the hydrolysis of butyrylthiocholine to thiocoline and butyrate. Thiocholine reduces the yellow substrate hexacyanoferrate III to the almost colorless hexacyanoferrate II. The decrease in color is measured spectrophotometrically. The calibrator is the Calibrator for automated systems (C.f.a.s; and the recommended control materials are Precinorm U or Precinorm U Plus; and Precipath U or Precipath U plus.

The Sentinel Cholinesterase Liquid assay is used to measure cholinesterase in human specimens. There are two principal type of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is note present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition and disorders. For In Vitro diagnostics use only. CFR 862.3240

Sentinel Cholinesterase Liquid is an in vitro diagnostic assay for the quantitative determination of cholinesterase in serum and plasma.

Reagent for the determination of cholinesterase concentrations in human serum and plasma using the Olympus family of clinical chemistry analyzers. Measurement of serum cholinesterase has been used to assess liver function and to investigate the variants of cholinesterase enzyme. It is also useful in predicting susceptibility to prolonged apnea after the administration of succinylcholine and in monitoring excessive exposure to organophosphorus insecticides.

The WIENER LAB. Colinesterasa AA test system is a quantitative in vitro diagnostic device intended to be used in the quantitative determination of cholinesterase (an enzyme that catalyzes the hydrolysis of acetylcholine to choline) in human specimens, on both manual and automated systems. There are two principal types of cholinesterase in human tissues. True cholinesterase is present at nerve endings and in erythrocytes (red blood cells) but is not present in plasma. Pseudo cholinesterase is present in plasma and liver but is not present in erythrocytes. Measurements obtained by this device are used in the diagnosis and treatment of cholinesterase inhibition disorders (e.g., insecticide poisoning and succinylcholine poisoning).

Kinetic Method. The principle is based on the following reaction system: Cholinesterase Butyrylthiocholine + H2O -> Thiocholine + Butyrate Thiocholine + DTNB -> 2-Nitro-5-Mercapto-benzoate The cholinesterase activity is determined by measuring the rate of absorbance change at 405 nm. DTNB: 5,5'-Dithiobis-2-Nitrobenzoic Acid. ChE: serum or plasma cholinesterase.
