  • Kits for a selective assay for determining the identity of live microorganisms in a mixed culture
    Publication number: 20040023208
    Abstract: The invention provides methods for determining the identity of an unknown live microorganism in a mixed culture. The microorganism can be a bacterium, fungus, virus, or protozoan. The invention further provides an assay for determining the ability of a selected microorganism in a mixed culture to replicate in the presence of a chemical agent. Kits for determining the identity of a live microorganism in a mixed culture and for determining the ability of a microorganism in a mixed culture to replicate are also provided.
    Type: Application

  • Method for washing magnetic particles in a vessel with a bottom pull
    Patent number: 5264042
    Abstract: An apparatus for washing pellets of magnetic particles magnetically bound to the bottom of a test tube employs a liquid handling probe having an aspiration channel with a forked inlet for positioning the probe onto the periapical region of the test tube for optimizing both the aspiration and expression of liquids. While contacting the periapical region of the test tube, the forked inlet may aspirate liquid adjacent to the pellet without contacting the magnetic particles. Furthermore, the contact between the forked inlet and the periapical region of the test tube, serves to position the outlet of the liquid channel directly over the pellet for dislodging and resuspending the magnetically bound pellet with a forceful stream of wash liquid.
