Abstract:

The present invention provides systems and processes for the collection and identification of macromolecules, such as biologically-derived macromolecules (e.g., proteins and nucleic acids), by measuring and comparing the molecular weight signatures of macromolecular samples. Reproducible molecular weight signatures provides reliable sample identification. In the case of viruses, proteomic molecular weight signatures can be used for identifying viral agents.

International Classification:

C12Q001/68
C12M001/34

US Classification:

435006000, 435287200, 435288500

Abstract:

Disclosed are microflulidic chips that include a plurality of vias; a functionalized porous polymer monolith capable of being in fluid communication with a via; a microarray capable of being in fluid communication with the functionalized porous polymer monolith; and an observation port through which at least one target disposed within the microarray is capable of being detected. The disclosed microfluidic chips contain microarrays that can be effectively coupled to functionalized porous polymer monoliths for capturing and concentrating sample nucleic acids. Also disclosed are microfluidic chips containing microarray probes having observation ports that enable the preparation of microarrays and the detection of targets. These microfluidic chips are capable of capturing and concentrating genetic material for the analysis and identification of biological organisms, such as so-called “threat genes” from chimeric bioweapons.

Appl. No.:

11/402656

Inventors:

Kyle W. Hukari - San Ramon CA, US
Jason A.A. West - Castro Valley CA, US

International Classification:

C12Q 1/00
C12M 3/00

US Classification:

435 4, 4352871

Abstract:

The present invention relates generally to systems and methods for processing a biological sample that result in a physical change, such as reacting two molecules together to form a reaction product or for use in lysing viruses or biological cells for analysis using biological assay systems. As such, the present invention relates both to breaking apart biological species such as viruses and cells, as well as the formation of reactants from one or more reactive species. The sample has a volume in the range from about 1 microliter to 10 milliliters. The sample is processed by applying pressure, and either sonic energy or thermal energy to the sample, wherein the pressure achieved is usually at least 24 atmospheres, and the temperature of the sample is usually raised to at least 50 C.
