摘要:
Novel carboxyalkylated disopyramides (NORPACE.RTM.) are provided as precursors for conjugating proteins, either antigenic for the preparation of antibodies or enzymatic for the preparation of enzyme conjugates, which antibodies and enzyme conjugates find use as reagents in immunoassays. The combination of antibodies and enzyme conjugates provide for sensitive, accurate, rapid assays for disopyramide without interference from closely analogous compounds, such as methadone or disopyramides metabolites.
摘要:
Chloramphenicol derivatives are provided for use in the preparing of antigen conjugates for the production of antibodies specifically for chloramphenicol. Specifically, the aryl amino group is derivatized to introduce a non-oxocarbonyl group which is used for amide formation with an antigen. The conjugate is then injected into a vertebrate for production of antisera which is isolated in conventional ways and finds particular use in competitive protein binding assays.

摘要:
Tricyclic antidepressant functionalized compounds are provided for conjugation through a side chain to antigenic compounds, particularly poly(amino acids), and enzymes. The antigenic conjugates are employed for the production of antibodies and together with the enzyme conjugates find particular use in immunoassays for the determination or detection of the total amount of tricyclic antidepressants present in a sample.

摘要:
Theophylline derivatives are provided for preparing reagents for use in competitive protein binding assays and for use as reagents in competitive protein binding assays. Theophylline is substituted at the 3 position and conjugated to antigens for production of antibodies which specifically recognize theophylline as distinct from structurally similar analogs such as caffeine. Enzyme conjugates are provided which find use for measuring the amount of theophylline in a sample suspected of containing theophylline. A method is provided employing the reagents for the determination of theophylline.
摘要:
A method for capturing an electronic signature of a user in a java based environment on a personal digital assistant. The method including prompting the user by an applet operating on the personal digital assistant, handling a canvas by the applet, and capturing an instance of the electronic signature on the canvas. The method further includes encoding by the canvas the instance of the electronic signature in a file and transferring the file by the canvas to the applet. A personal digital assistant including a screen sensitive to pressure for capturing a signature and an application adapted to capture the signature and attach the signature to a business object. In the personal digital assistant, the application further includes an applet adapted to prompt a user and adapted to handle a canvas. The canvas is adapted to capture an instance of the electronic signature and encode the instance in a file. The file is transferred by the canvas to the applet. A computer readable medium including a method for capturing an electronic signature of a user in a java based environment on a personal digital assistant.
摘要:
Nortriptyline functionalized compounds are provided for conjugation to antigenic compositions, particularly poly(amino acids), and enzymes. The antigenic conjugates are employed for the production of antibodies, which find use in immunoassays for the determination of nortriptyline in a sample, while the enzyme conjugates find use in an enzyme assay for the determination of nortriptyline in a sample.
摘要:
Methods and devices are provided for carrying out assays with minimal technical training where quantitative visual determinations may be made. The devices provide for a flow-path where a sample receiving element is moved from a sample receiving position to a position where it serves to bridge a transport element and a measurement element, so that the sample may be transported from the sample element to the measurement region. Labelled conjugates are provided which migrate a distance into the measurement region related to the amount of analyte in the sample.
