Patent ID: 10981960

Abstract:
The purpose of the present invention is to provide: a liver-type fatty acid-binding protein standard by which, in a measurement using a specifically binding substance, the range of variation of a measured value caused by a liver-type fatty acid-binding protein can be narrowed; a method of evaluating the standard; a method of drawing a calibration curve of a liver-type fatty acid-binding protein; and a method of quantifying the protein. A liver-type fatty acid-binding protein standard in which a coefficient of change in oxidation, said coefficient being represented by the ratio of a measured value obtained by using a liver-type fatty acid-binding protein standard having been subjected to an oxidation treatment with 10 mM of an oxidant for 1 hour at 25° C. to a measured value obtained by using the liver-type fatty acid-binding protein standard not subjected to the oxidation treatment, is set to 1.4 or less; a liver-type fatty acid-binding protein to be used in the standard; a DNA encoding the protein; a cell transformed by the DNA; a method of producing the protein; a method of evaluating the standard; a method of regulating the variation range of a measured value in a measurement using the standard; a method of drawing a calibration curve for the protein; and a method of quantifying the protein.
