International Classification:

B01D 59/44
H01J 49/00

US Classification:

250282, 250281

Abstract:

Relative quantitative information about components of chemical or biological samples can be obtained from mass spectra by normalizing the spectra to yield peak intensity values that accurately reflect concentrations of the responsible species. A normalization factor is computed from peak intensities of those inherent components whose concentration remains constant across a series of samples. Relative concentrations of a component occurring in different samples can be estimated from the normalized peak intensities. Unlike conventional methods, internal standards or additional reagents are not required. The methods are particularly useful for differential phenotyping in proteomics and metabolomics research, in which molecules varying in concentration across samples are identified. These identified species may serve as biological markers for disease or response to therapy.

Filed:

May 29, 1998

Appl. No.:

9/086993

Inventors:

Joanna M. Hunter - Redwood City CA
Hua Lin - Alameda CA
Christopher H. Becker - Palo Alto CA

Assignee:

GeneTrace Systems Inc. - Alameda CA

International Classification:

H01J 4404

US Classification:

250288

Abstract:

A sample preparation method is disclosed for volatilization and mass spectrometric analysis of nonvolatile high molecular weight molecules. Photoabsorbing molecules having significant sublimation rates at room temperature under vacuum, and preferably containing hydroxy functionalities, are disclosed for use as matrices in matrix-assisted laser desorption/ionization mass spectrometry. The samples are typically cooled in the mass spectrometer to temperatures significantly below room temperature.

Appl. No.:

16/821285

Inventors:

- Menlo Park CA, US
Hua Lin - Fremont CA, US

International Classification:

C12Q 1/04
C12M 1/12

Abstract:

Various examples are directed to kits, apparatuses, and methods for determining a presence of (BP) in a biological sample. An example method includes causing a physical interaction between a biological sample from a subject and a set of first agents by exposing the biological sample to the set of first agents, the set of first agents being specific to one or more of a set of BP biomarkers associated with one or more proteins released from BP or associated with other molecules released from BP. The method further includes determining a presence of BP in the biological sample based on detected binding between one or more of the set of first agents and the one or more of the set of BP biomarkers.
