  • Patent number: 5851777
    Abstract: The present invention provides methods for detecting the presence of or determining the amount of a ligand in a fluid sample. The methods comprise providing a first reagent comprising a sol particle having a detectable physical property bound to the ligand or ligand analogue (in a competitive format) or a substance capable of specifically coupling with the ligand (in a sandwich format), providing a second reagent having a detectable physical property comprising a sol particle bound to a substance capable of specifically coupling with the ligand and/or ligand analogue, if present, combining the first reagent, second reagent and the fluid sample and detecting before, during or after the reaction, a change in the physical property of the sol particles, which provides a qualitative or quantitative indication of the ligand in the fluid sample.

  • Patent number: 5759798
    Abstract: The invention provides assays, kits and bacteria useful for detection of autoinducers. In a preferred aspect, the assay comprises 1) contacting a test sample suspected of containing an autoinducer with bacteria of the invention that are capable of producing an elevated amount of light in the presence of an exogenous autoinducer and that has at least two distinct genetic alterations that can each inhibit production of endogenous autoinducers; and 2) measuring the production of light. The sample will test positive for the presence of an autoinducer if a greater amount of light is produced relative to a control. The assays and kits have a variety of applications including use as an in vitro diagnostic for animal and plant disorders.

  • Patent number: 5665570
    Abstract: A bacterium of the genus Bacillus is transformed by introducing a vector incorporating DNA encoding an antibody; the resulting transformant is cultivated in a medium to produce and accumulate the antibody in an active form in the culture liquid. According to this method, a recombinant antibody can be easily produced in an active form in large amounts, owing to success in secretory expression using a bacterium of the genus Bacillus.

  • Patent number: 5602037
    Abstract: The present invention provides novel test cartridges for use in the assay of liquid samples and methods of carrying out such assays. These test cartridges are particularly useful in assays which include at least one step during which the sample to be assayed and one or more components of the assay system are kept separated by a pierceable member. The test cartridges comprise a housing through which the sample flows during the assay. The housing includes a holding chamber for holding the sample and a test chamber separated by a pierceable member. The test chamber further includes a partition member which has an opening therethrough and includes at least one reagent for the assay. A transfer member movably mounted in the test chamber can move towards and pierce the pierceable member and contact the liquid sample in the holding chamber.
