US Patent:

20090042255, Feb 12, 2009

Filed:

Jul 22, 2008

Appl. No.:

12/177579

Inventors:

Jason Yingjie Liu - Foster City CA, US

International Classification:

C12P 19/34

US Classification:

435 911

Abstract:

A method for selectively recovering nucleic acid from a sperm cell in a sample containing cells of at least a sperm cell and an epithelial cell, and a cell suspension medium comprising extracellular impurities, is provided. The method entails introducing a sample into a vessel, sequestering the cells from the remaining sample components, washing the cells with a washing solution either before or after sequestration, removing the impurities-containing cell suspension medium from the vessel while retaining the cells; lysing selectively cells of the first cell type; and isolating the nucleic acid from the lysed cells. Methods for recovering nucleic acid from the second cell type are also provided.

US Classification:

435 61, 435219, 435220, 435221, 435262

Abstract:

The present teachings relate to the extraction of nucleic acid from solid materials. Provided are useful compositions, methods and kits for obtaining nucleic acids from a solid biological sample or an adhesive material having a biological material adherent or embedded within the adhesive substrate. The extracted nucleic acid can be used in downstream applications such as genotyping, detection, quantification, and identification of the source of the biological material.

Assignee:

LIFE TECHNOLOGIES CORPORATION - Carlsbad CA

International Classification:

G06T 7/00

US Classification:

382124

Abstract:

Systems, methods, and kits are disclosed for collection, labeling and analyzing biological samples containing nucleic acid in conjunction with collecting at least one ridge and valley signature of an individual. Such devices and methods are used in forensic, human identification, access control and screening technologies to rapidly process an individual's identity or determine the identity of an individual.

Inventors:

- Carlsbad CA, US
Jason Yingjie LIU - Foster City CA, US

International Classification:

C12Q 1/6851
C12Q 1/6806
C12Q 1/686

Abstract:

A workflow for direct qPCR quantification of unprocessed forensic casework samples is disclosed herein. 13 pg of DNA has been detected by direct amplification from a paper substrate. Direct qPCR quantification of unprocessed forensic casework samples and direct STR amplification of unprocessed forensic casework samples collected on the same PE-swab will greatly increase forensic laboratory's efficiency and capability.
