Hydrophilic, chemiluminescent acridinium compounds containing zwitterions are disclosed. These acridinium compounds, when used as chemiluminescent labels in immunochemistry assays and the like, exhibit decreased non-specific binding to solid phases and provide increased assay sensitivity.

The invention relates to an artificial antigen and antibody that is used for analyzing sulfa plural residual immunity and the manufacturing method. It uses 4-(4- amino benzene sulfonyl) benzoic acid as hapten and compound artificial antigen with carrier protein and taking animal immunity to make antibody that could be used to rapidly test the residual to sulfa. It has good broad spectrum feather and has great application prospect.

Methods for enhancement in accuracy of immunochemical analysis of heterogeneous biological fluids containing exogenous substances that can interfere in immunochemical analysis for endogenous analytes of interest. According to this method a heterogeneous biological fluid sample is pretreated with an interferant suppression effective amount of a molybdenum coordination complex, so as to reduce manifestation of the presence of said exogenous material under immunoassay conditions. This invention is suitable for the suppression of manifestation of exogenous substances, specifically metabolites of drugs of abuse, during the immunoassay of biological fluids of infants for detection of endogenous substances indicative of a wellness or disease state. This invention also has application for similar suppression exogenous substances in the biological fluid of adults that have been inadvertently exposed to such substances (e.g. secondhand smoke).

This invention relates to one cypermethrin human antigen process method in immune chemical analysis technique field, which comprises chrysanthemumic acid into alcohol liquid for centrifugation and taking for upper clear liquid for use; then taking cow blood serum protein and carbodiimide into sterilized water; then dripping by mixing into the protein liquid with chrysanthemumic acid and carbodiimide liquid for light shield reaction in ice; dripping remaining carbodiimide liquid into the above mixture liquid for continuing shield reaction; through centrifugation to take dialysis through cooling to get human antigen.

This invention discloses one enzyme immune test method and agent case for 3- methyl quinoline 2-carboxyl acid in immune chemical analysis technique field, which comprises the following steps: processing immune antigen and cover antigen and alloantibody and pre-processing sample and establishing ELISA method; the matched agent case is composed of 3- methyl quinoline 2-carboxyl acid alloantibody covered by MQCA and egg albumin couple and MQCA standard sample; the sample is processed through metaphosphoric acid to release MQCA and MAX and indirectly competition ELISA method.

The invention relates to a preparation method of a benzothiostrobin antigen and antibody and an application thereof, belonging to the technical field of immunochemical analysis. The chemical name of benzothiostrobin is 2-[[(5-methoxy-2-benzothiazole)-thiomethyl]-alpha-(E)-methoxymethylene]methyl phenylacetate. Under an alkaline condition, carboxylic ester in the benzothiostrobin structure is hydrolyzed to synthesize an artificial hapten of which the chemical name is 2-[[(5-methoxy-2-benzothiazole)-thiomethyl]-alpha-(E)-methoxymethylene]phenylacetic acid; the artificial hapten is coupled with bovine serum albumin and ovalbumin respectively to prepared an artificial antigen. The BALB / c female mouse is immunized by the artificial antigen to obtain a specific monoclonal antibody of benzothiostrobin. The antibody does not experience a cross reaction with other compounds. An enzyme linked immunosorbent assay method established by use of the antibody can be applied to quick, sensitive, convenient and cheap detection of benzothiostrobin residues in environment and agricultural products.
