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.

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.

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.

Abstract: Devices, methods, and kits are disclosed for collection, labeling and analysis of samples containing a substance of interest. Such devices and methods are used in forensic, human identification, access and importation control, and other investigative technologies to collect even limited amounts of a substance of interest that may be present on a substrate and to facilitate analysis to identify the substance of interest.

Abstract: Devices, systems, methods, and kits are disclosed for amplifying small quantities of nucleic acid and identifying the nucleic acid sequences of the amplified nucleic acid products.

Abstract: An identity authentication system includes a storage unit, a display character set generation unit, a display unit and a password authentication unit. An identity authentication method includes the following steps: generating the dynamic display character sets; inputting a dynamic input code; and comparing the dynamic input code with the user password. This invention can improve the security of identity authentication and is convenient to use.

Abstract: A workflow for direct qPCR quantification of unprocessed forensic casework samples is disclosed herein. 13pg 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.

Abstract: Methods are provided for differential extraction of DNA from at least two different cell types. Systems for carrying out the differential extraction methods are also provided. A kit is also provided for differential extraction of DNA from at least two different cell types using a multi-compartment container.
