The total cholesterol assay system included an amperometric peroxidase electrode to measure hexacyanoferrate(III) converted from hydrogen peroxide, which was generated by injecting a 2 µL sample into the packed-bed reactors of immobilized cholesterol esterase and cholesterol oxidase covalently bound to silica. The free cholesterol was assayed with the same system without the cholesterol esterase reactor. The peak current was linearly related to cholesterol in the range 2-160 mg/dl and to total cholesterol in the range 3-300 mg/dl; the assay speed was about 80 samples/h for free cholesterol and 40 samples/h for total cholesterol. Reliable results were obtained in the assays of free cholesterol and total cholesterol in human sera. Both the reactors and the peroxidase electrode retained over 90% of their original activities, even after repetitive use for 4 and 2 months, respectively. Cholesterol esterase and cholesterol oxidase were separately immobilized on silica packed into columns (length 10 and 30 cm, respectively). The injection of a sample (2 µL) containing cholesterol (free and/or esterified) resulted in generation of H2O2 by the immobilized enzymes, and the H2O2 was used to generate Fe(CN)63- from Fe(CN)64- in an immobilized peroxidase electrode. The Fe(CN)63- could be measured amperometrically at low potential (-50 mV vs. silver - Ag+), so that there was little interference from other normal constituents of serum. Free cholesterol was assayed by omission of the cholesterol esterase reactor. The peak current was rectilinearly related to cholesterol concentration. in the range 2 to 160 mg dl-1 or cholesteryl palmitate concentration. in the range 3 to 300 mg dl-1. About 80 samples h-1 could be assayed for free cholesterol or 40 h-1 for total cholesterol. Within-assay coefficient of variation were <1.5%. Results agreed well with those from a chemical method.

The total cholesterol assay system included an amperometric peroxidase electrode to measure hexacyanoferrate(III) converted from hydrogen peroxide, which was generated by injecting a 2 µL sample into the packed-bed reactors of immobilized cholesterol esterase and cholesterol oxidase covalently bound to silica. The free cholesterol was assayed with the same system without the cholesterol esterase reactor. The peak current was linearly related to cholesterol in the range 2-160 mg/dl and to total cholesterol in the range 3-300 mg/dl; the assay speed was about 80 samples/h for free cholesterol and 40 samples/h for total cholesterol. Reliable results were obtained in the assays of free cholesterol and total cholesterol in human sera. Both the reactors and the peroxidase electrode retained over 90% of their original activities, even after repetitive use for 4 and 2 months, respectively. Cholesterol esterase and cholesterol oxidase were separately immobilized on silica packed into columns (length 10 and 30 cm, respectively). The injection of a sample (2 µL) containing cholesterol (free and/or esterified) resulted in generation of H2O2 by the immobilized enzymes, and the H2O2 was used to generate Fe(CN)63- from Fe(CN)64- in an immobilized peroxidase electrode. The Fe(CN)63- could be measured amperometrically at low potential (-50 mV vs. silver - Ag+), so that there was little interference from other normal constituents of serum.

The total cholesterol assay system included an amperometric peroxidase electrode to measure hexacyanoferrate(III) converted from hydrogen peroxide, which was generated by injecting a 2 µL sample into the packed-bed reactors of immobilized cholesterol esterase and cholesterol oxidase covalently bound to silica. The free cholesterol was assayed with the same system without the cholesterol esterase reactor. The peak current was linearly related to cholesterol in the range 2-160 mg/dl and to total cholesterol in the range 3-300 mg/dl; the assay speed was about 80 samples/h for free cholesterol and 40 samples/h for total cholesterol. Reliable results were obtained in the assays of free cholesterol and total cholesterol in human sera. Both the reactors and the peroxidase electrode retained over 90% of their original activities, even after repetitive use for 4 and 2 months, respectively. Cholesterol esterase and cholesterol oxidase were separately immobilized on silica packed into columns (length 10 and 30 cm, respectively). The injection of a sample (2 µL) containing cholesterol (free and/or esterified) resulted in generation of H2O2 by the immobilized enzymes, and the H2O2 was used to generate Fe(CN)63- from Fe(CN)64- in an immobilized peroxidase electrode. The Fe(CN)63- could be measured amperometrically at low potential (-50 mV vs. silver - Ag+), so that there was little interference from other normal constituents of serum. Free cholesterol was assayed by omission of the cholesterol esterase reactor. The peak current was rectilinearly related to cholesterol concentration. in the range 2 to 160 mg dl-1 or cholesteryl palmitate concentration. in the range 3 to 300 mg dl-1. About 80 samples h-1 could be assayed for free cholesterol or 40 h-1 for total cholesterol. Within-assay coefficient of variation were <1.5%. Results agreed well with those from a chemical method.

The total cholesterol assay system included an amperometric peroxidase electrode to measure hexacyanoferrate(III) converted from hydrogen peroxide, which was generated by injecting a 2 µL sample into the packed-bed reactors of immobilized cholesterol esterase and cholesterol oxidase covalently bound to silica. The free cholesterol was assayed with the same system without the cholesterol esterase reactor. The peak current was linearly related to cholesterol in the range 2-160 mg/dl and to total cholesterol in the range 3-300 mg/dl; the assay speed was about 80 samples/h for free cholesterol and 40 samples/h for total cholesterol. Reliable results were obtained in the assays of free cholesterol and total cholesterol in human sera. Both the reactors and the peroxidase electrode retained over 90% of their original activities, even after repetitive use for 4 and 2 months, respectively. Cholesterol esterase and cholesterol oxidase were separately immobilized on silica packed into columns (length 10 and 30 cm, respectively). The injection of a sample (2 µL) containing cholesterol (free and/or esterified) resulted in generation of H2O2 by the immobilized enzymes, and the H2O2 was used to generate Fe(CN)63- from Fe(CN)64- in an immobilized peroxidase electrode. The Fe(CN)63- could be measured amperometrically at low potential (-50 mV vs. silver - Ag+), so that there was little interference from other normal constituents of serum. Free cholesterol was assayed by omission of the cholesterol esterase reactor. The peak current was rectilinearly related to cholesterol concentration. in the range 2 to 160 mg dl-1 or cholesteryl palmitate concentration. in the range 3 to 300 mg dl-1. About 80 samples h-1 could be assayed for free cholesterol or 40 h-1 for total cholesterol. Within-assay coefficient of variation were <1.5%. Results agreed well with those from a chemical method.

This electrode operates at only ~-50 mV vs. silver - Ag+, so that little interference is caused by other constituents of serum or urine. The peak current is rectilinearly related to uric acid concentration. in the range 0.2 to 8 mg dl-1. The peak width is ~30 s, so that 90 to 120 samples can be analyzed in 1 h with a coefficient of variation of 1 to 2%. Results show excellent agreement with those by the urate oxidase - u.v. method.', 'language' => 'Japanese', 'updated' => '2020-12-28 11:25:15', 'sjccheck' => 'No', 'sjccheckdate' => '0000-00-00 00:00:00', 'hits' => '0', 'urlcheck' => '2014-10-12 00:27:39', 'urlcheckcode' => 'HTTP/1.1 302 Found', 'pauthor_id' => null, 'pauthor' => 'NA', 'address' => 'Univ.
