Abstract:
Nucleic acid from cells and viruses sampled from a variety of environments may purified and expressed utilizing microfluidic techniques. In accordance with one embodiment of the present invention, individual or small groups of cells or viruses may be isolated in microfluidic chambers by dilution, sorting, and/or segmentation. The isolated cells or viruses may be lysed directly in the microfluidic chamber, and the resulting nucleic acid purified by exposure to affinity beads. Subsequent elution of the purified nucleic acid may be followed by ligation and cell transformation, all within the same microfluidic chip. In one specific application, cell isolation, lysis, and nucleic acid purification may be performed utilizing a highly parallelized microfluidic architecture to construct gDNA and cDNA libraries.
Abstract:
The invention provides polypeptides, including enzymes, structural proteins and binding proteins, polynucleotides encoding these polypeptides, and methods of making and using these polynucleotides and polypeptides. Polypeptides, including enzymes and antibodies, and nucleic acids of the invention can be used in industrial, experimental, food and feed processing, nutritional and pharmaceutical applications, e.g., for food and feed supplements, colorants, neutraceuticals, cosmetic and pharmaceutical needs. Polypeptides of the invention can be used in food processing, brewing, bath additives, alcohol production, peptide synthesis, enantioselectivity, hide preparation in the leather industry, waste management and animal degradation, silver recovery in the photographic industry, medical treatment, silk degumming, biofilm degradation, biomass conversion to a biofuel (e.g., a bioethanol, biomethanol, biopropanol or biobutanol, a biodiesel, etc.), biodefense, antimicrobial agents and disinfectants, personal care and cosmetics, biotech reagents, in corn wet milling and pharmaceuticals such as digestive aids and anti-inflammatory (anti-phlogistic) agents.
