Abstract: A biological analysis system includes a probe. The probe is configured to dispense a biological sample into a first chamber. The system also includes a pump. The pump is configured to convey a first delivery of diluent to the first chamber for mixing with the biological sample to produce a sample mixture, aspirate a portion of the sample mixture from the first chamber, and convey the portion of the sample mixture to a second chamber. A method of analyzing a biological sample includes conveying a diluent to a first chamber via a first pump, dispensing a blood sample into the first chamber via a probe to produce a sample mixture, and conveying a portion of the sample mixture from the first chamber to a second chamber via the first pump.

Abstract: Techniques for the sensitive detection of analytes which combine the benefits of solution/suspension phase assay formats and the simplicity of solid phase/lateral flow assays are described. The assays can be performed in the solution/suspension phase using magnetic microspheres as a solid support. Subsequently a magnetic separation can be performed to separate the bound analyte from the remainder of the solution. After a wash step, the fluorescence signal can be directly read from the magnetic particle surface. Portable biodetection systems which employ fluorescent polymer superquenching and methods for detecting bioagents therewith are also described.

Abstract: High throughput electrophoresis having a plurality of samples migrating through a highly resistive separatory media under an electric field. Multiple electrophoresis runs are conducted using a single separatory media. Automated methods of data analysis yields quantitative and qualitative data using optical densitometer or other detection systems. Controlled operating temperatures and small geometry reduces dispersion inaccuracy in banded data.
