Patents by Inventor Lawrence J. Blecka

Lawrence J. Blecka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8012768
    Abstract: The present invention provides a system and method for the simultaneous detection of multiple analytes in a sample. The detection system includes a housing that holds a reagent carousel rotatably coupled thereto. Further included in the housing is an incubator carousel rotatably coupled thereto. The housing also includes magnetic material that is associated with the incubation carousel for assisting in separation beads from reagent and wash solution. A robot, associated with the housing is configured to manipulate at least either the reagent carousel or the incubator carousel and transfer materials between these carousels. Reaction vessels hold samples and reaction vessels handlers move the reaction vessels. Sample analysis is determined by at least one laser based detector.
    Type: Grant

  • Patent number: 7267940
    Abstract: The present invention relates to peptides that are derived from HSV-2 glycoprotein G2 and represent HSV-2 type-specific epitopes. The present invention also provides for compositions comprising these peptides for type-specific serological diagnosis of HSV-2 infection. Methods of using these peptides for type-specific detection of HSV-2 antibodies and differentiation of HSV-2 viral infection from HSV-1 and other herpes family viral infections are further provided.

  • Patent number: 7000785
    Abstract: A tube rack for holding and transporting sample tubes or other liquids in an automated analyzer is built to accommodate tubes of different sizes in a stable aligned configuration, the rack containing a row of parallel open-top tube chambers, each chamber containing two sets of resilient tabs integrally molded with the chamber walls and at different heights in the chamber.

  • Patent number: 5006473
    Abstract: The electrophoresis method of the present invention employs a media which contains uniformly dispersed liposomes of phospholipid, or combinations of phospholipid and neutral lipid, which contain chromogenic materials or dye precursers. After electrophoresis of a test sample, the liposomes are lysed and the chromogen or dye material released. The chromogen or dye can be any signal producing substance including a chromogenic agent, and enzyme, a fluorogenic agent, or a chemiluminescent agent, but a detectable signal occurs only where the staining material is in close proximity to specific enzymes, effectors, analytes, or other color-inducing agents which have migrated through the gel during electrophoresis.
