    摘要： A diffraction immunoassay method in which a diffraction grating design of non-light disturbing primary binding reagent on an insoluble surface is conjugated with analyte in a sample. If the primary binding reagent-analyte conjugate is light disturbing, a diffraction grating is formed. If the primary binding reagent-analyte conjugate is non-light disturbing, the analyte is further conjugated with a secondary binding reagent which is labeled with a light disturbing material to form a diffraction grating. Light from a narrow band light source is then applied to the surface, and the intensity of beams of diffracted light formed by the diffraction grating is determined. The diffraction immunoassay plate for the method comprises a smooth insoluble surface having on the surface thereof, a diffraction grating design of lines of the primary binding reagent. The diffraction immunoassay apparatus comprises a light source, a platform for supporting the diffraction immunoassay plates in the path of a beam of light from the light source, and at least one light detector positioned to detect light diffracted by the diffraction grating.

    摘要翻译： 衍射免疫测定方法，其中在不溶性表面上的非光干扰的初级结合试剂的衍射光栅设计与样品中的分析物结合。 如果主要结合试剂 - 分析物共轭物是光线干扰的，则形成衍射光栅。 如果主要结合试剂 - 分析物缀合物是非光干扰的，则分析物进一步与用光干扰材料标记以形成衍射光栅的第二结合试剂缀合。 然后将来自窄带光源的光施加到表面，并且确定由衍射光栅形成的衍射光束的强度。 用于该方法的衍射免疫测定板包括在其表面上具有主要结合试剂线的衍射光栅设计的光滑不溶表面。 衍射免疫测定装置包括光源，用于在来自光源的光束的路径中支撑衍射免疫测定板的平台，以及定位成检测由衍射光栅衍射的光的至少一个光检测器。

    摘要： A composition, device and method for preparing a ketone control solution are disclosed. The composition comprises dimethylformamide and a Group I, II or III metal salt of a .beta.-keto acid ester. The salt has the structure ##STR1## in which R is lower alkyl of 1 to 6 carbon atoms, R' is an aliphatic or cyclic group having 1 to about 7 carbon atoms, M is a Group I, II or III metal ion and n is 1, 2 or 3. A carrier matrix incorporated with the composition can be affixed to a support member to form the device. Preferably, a hydrolyzing agent is included on the device in the same or another carrier matrix. The method for preparing the control solution comprises contacting a predetermined volume of an aqueous solution with the device for a predetermined time.
