  • Publication number: 20080242558
    Abstract: The present invention includes a method and composition of storing and preserving biofilms for input and output of high-density information. One form of the present invention is a fabricated biofilm storage device with a biologic material applied to a substrate to form, e.g., a dry thin film stable at room temperature for extended periods of time. Another form of the present invention is a method of fabricating a biofilm storage device in which a biologic material is applied to a substrate under conditions that promote alignment of the biologic material on the substrate. The composition, method, and kit of the present invention have universal application in biologics, magnetics, optics and microelectronics.

  • Patent number: 7094571
    Abstract: The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating binding proteins capable of binding small molecules and peptides. In the technique, libraries of candidate binding proteins, such as antibody sequences, are expressed in the periplasm of gram negative bacteria and mixed with a labeled ligand. In clones expressing recombinant polypeptides with affinity for the ligand, the concentration of the labeled ligand bound to the binding protein is increased and allows the cells to be isolated from the rest of the library. Where fluorescent labeling of the target ligand is used, cells may be isolated by fluorescence activated cell sorting (FACS). The approach is more rapid than prior art methods and avoids problems associated with the outer surface-expression of ligand fusion proteins employed with phage display.

  • Patent number: 7083945
    Abstract: The invention overcomes the deficiencies of the prior art by providing a rapid approach for isolating binding proteins capable of binding small molecules and peptides via “display-less” library screening. In the technique, libraries of candidate binding proteins, such as antibody sequences, are expressed in soluble form in the periplasmic space of gram negative bacteria, such as Escherichia coli, and are mixed with a labeled ligand. In clones expressing recombinant polypeptides with affinity for the ligand, the concentration of the labeled ligand bound to the binding protein is increased and allows the cells to be isolated from the rest of the library. Where fluorescent labeling of the target ligand is used, cells may be isolated by fluorescence activated cell sorting (FACS). The approach is more rapid than prior art methods and avoids problems associated with the surface-expression of ligand fusion proteins employed with phage display.

  • Publication number: 20030100023
    Abstract: The invention relates to novel competitive immunoassays that are useful in detecting and quantitatively measuring analytes down to the nanomolar range. The invention also includes methods of selecting antibodies from libraries of polypeptides expressed on a cell surface. In conducting immunoassays, anti-analyte antibody molecules are expressed on the surface of a bacterial cell and then used to bind with labeled analyte. Quantitation is performed by competitively displacing the bound labeled analyte with a known amount of analyte and measuring the label. The method is rapid and inexpensive and may be performed with readily available safe labeling reagents such as fluorescent compounds.

  • Patent number: 6180341
    Abstract: The present invention combines PCR™ mutagenesis with in vitro transcription/translation and ELISA for the rapid generation and characterization of protein mutants. The PCR™ products are used directly as the template for the in vitro transcription/translation reactions and because no cloning steps are required, the in vitro saturation mutagenesis of one residue can be completed in duplicate within a week by a single investigator. This high throughput enables the saturation mutagenesis of numerous residues of interest, a process that can be described as in vitro scanning saturation mutagenesis. Compositions and methods of use of such a process are described herein.
