  • Patent number: 9447462
    Abstract: The present invention provides methods for the quantification of an unknown bioagent in a sample by amplification of nucleic acid of the bioagent, and concurrent amplification of a known quantity of a calibration polynucleotide from which are obtained a bioagent identifying amplicon and a calibration amplicon. Upon molecular mass analysis, mass and abundance data are obtained. The identity of the bioagent is then determined from the molecular mass of the bioagent identifying amplicon and the quantity of the identified bioagent in the sample is determined from the abundance data of the bioagent identifying amplicon and the abundance data of the calibration amplicon.

  • Publication number: 20160180020
    Abstract: The present invention relates generally to the field of investigational bioinformatics and more particularly to secondary structure defining databases. The present invention further relates to methods for interrogating a database as a source of molecular masses of known bioagents for comparing against the molecular mass of an unknown or selected bioagent to determine either the identity of the selected bioagent, and/or to determine the origin of the selected bioagent. The identification of the bioagent is important for determining a proper course of treatment and/or irradication of the bioagent in such cases as biological warfare. Furthermore, the determination of the geographic origin of a selected bioagent will facilitate the identification of potential criminal identity.
