摘要:
A dry analytical element for quantitatively analyzing creatine kinase MB isozyme is composed of a support and a creatine kinase MB isozyme-detecting agent layer. The detecting layer contains an antibody which specifically inhibits activity of M sub-unit of creatine kinase, creatine phosphate and adenosine diphosphate which react with each other to give adenosine triphosphate in the presence of creatine kinase MB isozyme, a buffer compound which keeps the layer in the range of pH 5.5 to pH 8.5 for the formation of adenosine triphosphate, and an indicator composition which reacts with the formed adenosine triphosphate to give a spectroscopically detectable compound, said indicator composition having hexokinase, nicotinamide-adenine dinucleotide or its phosphate in an oxidized form, and glucose-6-phosphate dehydrogenase but not containing glucose in such amount as to give the spectroscopically detectable compound.

A dry analytical element for quantitatively analyzing creatine kinase is composed of a support and a creatine kinase-detecting agent layer. The creatine kinase-detecting agent layer contains creatine phosphate and adenosine diphosphate which react with each other to give adenosine triphosphate in the presence of creatine kinase, a buffer compound having a sulfonic acid group which keeps the layer in the range of pH 5.5 to pH 8.5 for the formation of adenosine triphosphate, and an indicator composition which reacts with the formed adenosine triphosphate to give a spectroscopically detectable compound. An analytical element for analysis of creatine kinase MB isozyme further contains in the layer an antibody which specifically inhibits activity of M sub-unit of creatine kinase.

A control serum for a dry process is provided that does not show misfit in measurement values by the dry process and a wet process. The above-mentioned control serum is obtained by freezing or freeze-drying a control serum without dialysis.
摘要:
A humoral testing apparatus in which a measuring light is irradiated to a reagent area forming a color as a result of a reaction and an optical density of the reagent area is detected by a detecting operation of light intensity of the reflected light. The humoral testing apparatus enables a humoral test to be performed accurately in cases where nonuniformity occurs with the reaction of a reagent with a humoral sample within the reagent area, or in cases where fine dust is present within each detecting spot in the reagent areas. The light reflected from the reagent areas is detected with a two-dimensional photodetector. The independent light intensity detecting operations are performed with respect to the subareas of the reagent area of a reagent layer. A photo detection signal S, which represents the intensity of the reflected light is statistically processed with a signal processing section 51.
摘要:
A blood testing unit comprises a closed vessel having a blood introducing section formed at a certain area of the closed vessel. A blood constituent separating section is located within the closed vessel to separate plasma and/or serum from the blood sample introduced through the blood introducing section into the closed vessel. A reagent layer is located within the closed vessel, such that the reagent layer can be seen from the exterior. The reagent layer comprises a region for spreading the plasma and/or the serum, which has been separated by the blood constituent separating section from the blood sample, and a reagent supporte donor in the spreading region, the reagent undergoing a reaction with the plasma and/or the serum and forming a color as a result of the reaction.

摘要:
A blood testing unit is provided with a closed vessel having an outer vessel body and an inner vessel body, and a reagent layer is accommodated in the closed vessel. Reagents which react with a blood sample are supported on the reagent layer. The closed vessel is comprised such that at least either one of the outer vessel body and the inner vessel body is provided with an aperture, through which air is capable of being introduced from the exterior to the interior of the one vessel body, and the one vessel body is provided with a sealing member for closing the aperture.
摘要:
A plurality of different kinds of reagents are supported at different positions on a reagent layer. A humoral testing apparatus irradiates measuring light which has a wavelength adapted to one of the plurality of the reagent areas which forms a color, and detects the intensity of the light reflected from the reagent areas with the photodetector with respect to each of the reagents, and thus detects the optical densities of the reagent areas.

A flight control surface such as a slat capable of keeping and achieving a minimum basic functions even when it is damaged by collisions of birds or the like, and a wing using the same are provided. Both ends of one wire cable 15 or more are fixed to paired ribs 10A and 10B provided in a short direction of the slat. This wire cable 15 is placed so as to pass through a through-hole 13 formed in each of the ribs 10 positioned between the paired ribs 10A and 10B. Even if birds or the like collide with slat 3 at the time of a flight of the aircraft to damage and deform not only a skin 4 of the slat 3 but also any rib 10, the wire cable 15 between the paired ribs 10A and 10B prevents the slat 3 from being broken into pieces.
摘要:
A high-purity silicon carbide powder and its production method enable mass production of the high-purity silicon carbide powder at low cost in a safe manner. The content of impurities in the silicon carbide powder is 500 ppm or less. The silicon carbide powder can be obtained by heating a raw material for silicon carbide production in an Acheson furnace using a heat generator. The raw material for silicon carbide production is prepared by mixing a siliceous raw material and a carbonaceous raw material. The raw material for silicon carbide production contains the siliceous raw material and the carbonaceous raw material at a mixture mole ratio (C/SiO2) of 2.5 to 4.0 and has a content of impurities of 120 ppm or less.
