  • Method for generating recombinant polynucleotides
    Publication number: 20040091886
    Abstract: A novel method for producing recombinant polynucleotides in vitro is provided. This method entails the treatment of heteroduplex DNA sequences with a nuclease (preferably, DNase I) and a polymerase (preferably, DNA polymerase I), the enzymes primarily involved in nick translation. The results achieved using this process are superior to that achieved by previous in vivo recombination efforts utilizing specific DNA repair systems.

  • Space borne high resolution hyperspectral imaging instrument optimized for the study of atmospheric constituents
    Patent number: 6734966
    Abstract: A high resolution hyperspectral imaging apparatus (10) for analyzing atmospheric constituents. The apparatus (10) includes an optical telescope that receives an optical beam to be analyzed. A beam splitter (20) separates the optical beam into a first beam and a second beam that have separate wavelengths. A first spectrograph (72) analyzes the first beam and a second spectrograph (74) analyzes the second beam. Both spectrographs (72, 74) include a lens assembly (36, 44), a grating (42, 50) and a detector (54, 52). The gratings (42, 50) separate the beams into representative wavelengths that are recorded by the detectors (54, 52).
