  • Publication number: 20140073530
    Abstract: The present invention describes methods of performing rapid nucleic acid detection using a flow through process. The methods comprise single-step signal amplification and/or a one-step hybridization protocol. Using the flow through hybridization process, the present invention provides a more efficient, faster and less expensive genotyping method. This invention further provides a Single Nucleotide Polymorphism (SNP)-based DNA fingerprinting method for rapid and accurate genotyping, identification as well as DNA analyses of genetic materials from human beings and other different organisms. In addition this invention also discloses devices for rapid and sensitive analysis of target analysts.

  • Patent number: 7732138
    Abstract: The present invention discloses the use of Allele-Specific-Oligonucleotide (ASO) as a detection assay for human HLA classification. Using Reversed-Dot-Blotting format and flow through hybridization process, more efficient, faster and less expensive HLA classification can be achieved. A simplified procedure for HLA genotyping is also described. This invention further provides a Single Nucleotide Polymorphism (SNP)-based DNA fingerprining method for rapid and accurate genotyping, identification as well as DNA analyses of genetic data from human beings and different organisms. In addition this invention also discloses a new device for rapid and sensitive analyses of nucleic acids, proteins and other analysts for diagnosis.

  • Patent number: 6968457
    Abstract: A method for making a secured personal identity card and procedures for validation and obtaining secure personal information includes the steps of (a) collecting a set of personal information from a user into an identity file wherein the identity file includes at least one section; (b) receiving an inputting personal identification number (“PIN”); and (c) comparing the inputting PIN with a master PIN preset in the identity file. Therefore, the user selectively and securely releases only specific information based upon the inputting PIN as compared to the biographical information guarded by the master PIN.
