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 therebetween. Reaction vessels hold samples and reaction vessels handlers move the reaction vessels. Sample analysis is determined by at least one laser based detector.

System and method for multi-analyte detection

Devices, including a wash ring assembly, and methods are provided for the removal of excess fluid or solids from the exterior or interior of a probe used to transfer fluids, for instance, in an automated assay device. Typically, a probe is used to aspirate and dispense a sample fluid material such as whole blood or a reagent. The devices and methods provided herein are useful for removing excess fluid from the exterior or interior of the probe so as to prevent dripping and cross-contamination between samples or reagents. It is also contemplated that, utilizing the devices and methods provided herein, washing and/or drying can be performed simultaneously as the probe is in motion, aspirating a sample and/or dispensing a sample.

Wash ring assembly and method of use

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.

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.

HSV-2 type-specific immunoassays using glycoprotein G2 peptides

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.
