    • 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.
    • 通过反射光的光强度的检测操作来检测其中测量光照射到由于反应而形成颜色的试剂区域和试剂区域的光密度的体液测试装置。 体液检测装置能够在试剂区域内的试剂与体液样品的反应发生不均匀的情况下,或者在试剂区域的每个检测点内存在微细粉尘的情况下,能够准确地进行体液检查。 用二维光电检测器检测从试剂区反射的光。 针对试剂层的试剂区域的子区域进行独立的光强度检测动作。 用信号处理部分51对表示反射光强度的光检测信号S进行统计处理。

    • 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.
    • 用于定量分析肌酸激酶MB同功酶的干燥分析元件由载体和肌酸激酶MB同工酶检测剂层组成。 检测层含有特异性抑制肌酸激酶,亚磷酸肌酸和磷酸腺苷的M亚单位的活性的抗体,其在肌酸激酶MB同功酶(一种保持该层的缓冲化合物)存在下相互反应,产生三磷酸腺苷 用于形成三磷酸腺苷的pH 5.5至pH 8.5的范围,以及与形成的三磷酸腺苷反应以产生光谱可检测化合物的指示剂组合物,所述指示剂组合物具有己糖激酶,烟酰胺 - 腺嘌呤二核苷酸或其氧化形式的磷酸酯 和葡萄糖-6-磷酸脱氢酶,但不含葡萄糖,其量使得可得到光谱可检测的化合物。
