  • Patent number: 7893007
    Abstract: In order to obtain a novel binding protein against a chosen target, DNA molecules, each encoding a protein comprising one of a family of similar potential binding domains and a structural signal calling for the display of the protein on the outer surface of a chosen bacterial cell, bacterial spore or phage (genetic package) are introduced into a genetic package. The protein is expressed and the potential binding domain is displayed on the outer surface of the package. The cells or viruses bearing the binding domains which recognize the target molecule are isolated and amplified. The successful binding domains are then characterized. One or more of these successful binding domains is used as a model for the design of a new family of potential binding domains, and the process is repeated until a novel binding domain having a desired affinity for the target molecule is obtained.

  • Patent number: 7413537
    Abstract: The invention relates, in part, to a library of chimeric proteins, each chimeric protein including a mini-protein between about eight and about forty amino acids long, wherein the mini-protein has a single disulfide bond formed by a pair of invariant cysteines and has only two cysteines. The chimeric protein also includes at least a portion of an outer surface protein of a genetic package, wherein the chimeric protein is displayed on the outer surface of the genetic package. The invention also includes, in part, a mixture of nucleic acids that encode a library of the invention. The invention also includes, in part, a process for identifying proteins with a desired binding activity against a target, the process including screening a library of chimeric proteins of the invention; and identifying the chimeric protein. The invention, in part, also includes chimeric proteins expressed by a library of the invention.

  • Patent number: 6906176
    Abstract: Novel enterokinase cleavage sequences are provided. Also disclosed are methods for the rapid isolation of a protein of interest present in a fusion protein construct including a novel enterokinase cleavage sequence of the present invention and a ligand recognition sequence for capturing the fusion construct on a solid substrate. Preferred embodiments of the present invention show rates of cleavage up to thirty times that of the known enterokinase cleavage substrate (Asp)4-Lys-Ile.
