An indirect agglutination immunoassay includes the steps of providing, in a container, an immunoassay system comprising a test sample containing a desired analyte, and a reagent composed of magnetic particles or magnetic-material containing particles containing iron therein, wherein the magnetic particles or magnetic-material containing particles have been sensitized to allow specific binding to the desired analyte, and have a particle size in the range of 1 to 5 &mgr;m, with the content of the iron being in the range of 8 to 20 wt. %, precipitating the magnetic particles or magnetic-material containing particles by the application of magnetic force, allowing the container to stand at an inclination, and detecting the presence or absence of an immune reaction from the absence or presence of slippage observed of the precipitated magnetic particles or magnetic-material containing particles on the bottom of the container. An apparatus for conducting this indirect agglutination immunoassay is composed of the above container, a magnetic sedimentation device for magnetically precipitating the components containing the magnetic particles at the bottom of the container, and an inclination device for allowing the container to stand at an inclination after removal of the magnetic sedimentation device.

In a miniaturized complete CMOS SRAM of a TFT load type, a field effect thin-film transistor (TFT) can achieve stable reading and writing operation of a memory cell and can reduce power consumption thereof. The field effect thin-film transistor formed on an insulator includes an active layer and a gate electrode. The gate electrode is formed on a channel region of the active layer with a gate insulating film therebetween. The active layer is formed of a channel region and source/drain regions. The channel region is formed of a monocrystal silicon layer and does not includes a grain boundary. The source/drain regions is formed of a polysilicon layer. The channel region has a density of crystal defects of less than 10.sup.9 pieces/cm.sup.2. The thin film transistor shows an ON current of 0.25 .mu.A/.mu.m per channel width of 1 .mu.m and an OFF current of 15 fA/.mu.m. The thin-film transistor can be applied to a p-channel MOS transistor serving as a load transistor in a memory cell of a CMOS type SRAM.

The invention discloses a low NO.sub.x emission burner for use with an apparatus in which the material or materials are heated by the heat radiated from the radiation surface which is heated by the combustion by the burners. The secondary air injection ports or outlets are so arranged as to inject the secondary air upon the radiation surface to control the combustion, thereby reducing the release of NO.sub.x without producing CO and soot.

摘要:
A novel artificial carrier is disclosed which is prepared from gelatin, a water-soluble polysaccharide, a sodium metaphosphate and an aldehyde. The carrier can be used to immobilize antibodies, antigens or enzymes. Immobilized antigens and antibodies can be used as a diagnostic reagent in assays involving antigen-antibody reactions.
