Abstract: The present invention relates to a Polymerase Chain Reaction and High Resolution Melt genetic identification system, and, more specifically, to a tactical and portable Polymerase Chain Reaction and High Resolution Melt genetic analysis and identification system that is configured to determine and communicate analysis and identification results and a tiered confidence/alert level related to the analysis and identification results.

Abstract: A real-time system for determining the geographic movements of an individual or object by sampling particulates contained thereon. The system includes particle collection, sample preparations, and sample analysis using three primary modes of detecting certain particulates. The first mode involves the imaging of pollen, spores, or other biological material which are visible through a light microscope when properly stained or prepared. The second mode involves the use of real-time polymerase chain reaction to amplify and detect target nucleic acid sequences. The third mode involves the use of X-ray diffraction to identify mineral particles. The results from any mode, or any combination of modes, are analyzed by comparison to a reference database containing geographic information and the results are compiled by a controller for visual display.

Abstract: Methods and compositions are provided for the detection of 2,4-dichlorophenoxyacetic acid (2,4-D) and other phenoxy ether compounds. The phenoxy ether bond of 2,4-D is enzymatically cleaved by 2,4-D .alpha.-ketoglutarate dioxygenase to form 2,4-dichlorophenol, which is assayed by the 4-aminoantipyrine method. The enzyme is supplied in a dried form, preferably immobilized on a solid support, and is stable at room temperature for several months even in a highly impure state, e.g., crude cell extracts or dried cells.
