- the method of measuring sulfate-conjugated bile acids is the solution method.
- No. 45183 discloses that sulfate-conjugated bile H "acid is first converted to 3 ⁇ 5-hydroxybile acid by using a sulfate-conjugated bile acid desulfate sulfate (hereinafter, abbreviated as” BSSJ ").
- BSSJ sulfate-conjugated bile acid desulfate sulfate
- 39-HSDJ 3-hydroxysteroid dehydrogenase
- NADs nicotinamide adenine dinucleotides
- NADPs nicotinamide dodenine dinucleotide phosphates
- a method for measuring the amount of NAD PHs (reduced NADPs) is disclosed.
- a desulfating enzyme fog is generated in the process of forming a solution net, and a uniform solution cannot be prepared because the solution is not uniformly separated, resulting in a measurement error.

- water-soluble synthetic polymers or water-soluble S-enzyme substances are used.
- the coloring of the background which may be due to the coloring of Tio NA D (Tio NA DH), is resolved.
- sugar alcohols is not particularly limited. If sugar alcohols are not used, the sulfuric acid will cause sticking during the process of producing the solution, and the storage stability of the composition in the test paper will be significantly reduced.
- sugar alcohols examples include D-sorbitol, D-mannitol and the like.
- compounds structurally similar to sugar alcohols, such as sucrose, glycerol, and boroyl such as polyethylene glycol can also be used.

- a method for producing the integrated multilayer analytical element of the present invention will be described.
- thio NAD + and NADH required for enzymatic cycling reaction in a buffer solution in advance.
- a solution of a water-soluble polymer previously dissolved in a buffer solution of the same type as above and the enzyme solution are mixed and thoroughly stirred.
- the mixed solution is uniformly spread on a support and dried to form a reagent layer.
- the developed layer is laminated, and further dried.
- undesired coloring may occur and the background may increase, but the use of water-soluble polymers, especially highly purified polyvinylpyrrolidone and phenol or burlan, will increase the background. Can be suppressed.
- test specimen raw material thus obtained is cut, adhered to a support with an adhesive tape, and cut to obtain a test specimen for measurement.
- the rise of a blank can be suppressed and the aggregation of nitrogen can be prevented at the time of conversion of the solution used at the time of forming a reagent layer.
- Laminate the spread layer by placing the paper impregnated with 0 »paper on top and applying pressure to adhere. Then, the raw test piece is obtained by drying. After applying a double-sided adhesive tape to the PET side of the obtained test piece raw material, it was cut into a predetermined size, and attached to a support (PET plate) with a double-sided adhesive tape to obtain a test piece.
- Each test piece prepared as described above was subjected to a K test using litcholylglycine 3-sulfate (hereinafter, abbreviated as “GLCAJ”) as a sample, for 110 seconds.
- GLCAJ litcholylglycine 3-sulfate
- the change in reflectivity afterward is measured using a special reflectometer (Spotke). M (Manufactured by Kyoto Dai-ichi Gaku Co., Ltd.).
- the unit of KZS is used, but this is the unit used to convert the reflectance to density. If the reflectance is R,
- This KZS ⁇ indicates a large value when the concentration of the substance to be measured contained in the sample is high, and a small value when the concentration is low.
- Example 1 the background was lowered, and sufficient sensitivity for measurement was obtained in proportion to the GLC A concentration.
- Figure 1 shows the change of the blank value at g. In Example 1, the value is found to be stable.
- PVP indicates polyvinylpyrrolidone.
