  • Patent number: 7192720
    Abstract: Reagents and methods for detecting target proteins in a sample are provided. The reagents include a replicable genetic package, a protein displayed on an exterior surface of the package that is expressed from a heterologous nucleic acid borne by the package, and one or more antibodies complexed with the expressed protein and which have an open binding site for a target protein. Thus, a segment of the nucleic acid encodes for an epitope that is shared by the expressed polypeptide and the target protein. The reagents can be utilized individually or as part of a library or an array to bind target proteins within protein samples to form one or more complexes. By determining the sequence of the segment of the heterologous nucleic acid of a package within a complex, one can identify the target protein since the segment encodes for an epitope that is shared by the expressed and target proteins.

  • Patent number: 7045313
    Abstract: Methods and compositions are provided for the use of vaccinia virus or other poxviruses as vectors for expression of foreign genes. Expression of foreign genes is obtained by combining vaccinia virus transcriptional regulatory sequence with uninterrupted foreign protein coding sequences in vitro to form a chimeric gene. The chimeric gene is flanked by DNA from a non-essential region of the vaccinia virus genome to provide sites for in vivo homologous recombination. These steps are facilitated by the construction of plasmids that contain multiple restriction endonuclease sites, next to the vaccinia transcriptional regulatory sequences, for insertion of any foreign protein coding sequence. Transfection procedures are used to introduce the DNA into cells where homologous recombination results in the insertion of the chimeric gene into a non-essential region of the vaccinia virus genome.

  • Patent number: 6998252
    Abstract: Recombinant poxviruses, such as vaccinia, are provided that comprises a segment comprised of (A) a first DNA sequence encoding a polypeptide that is foreign to poxvirus and (B) a poxvirus transcriptional regulatory sequence, wherein (i) said transcriptional regulatory sequence is adjacent to and exerts transcriptional control over said first DNA sequence and (ii) said segment is positioned within a nonessential genomic region of said recombinant poxvirus. Vaccines, carriers, cells, and media comprising recombinant poxviruses, and methods of immunization with recombinant poxviruses also are provided.

  • Patent number: 6979568
    Abstract: A vector expressing two foreign genes by using RRE sequence and controlling the ratio of the expression doses of these genes owing to the modification is provided. This vector, which can be provided as a lentivirus vector based on SIVagm, is constructed by modifying a virus-origin expression regulatory sequence into another expression regulatory sequence so as to eliminate the dependency on the virus-origin protein. Although this vector has a packaging signal, it has been modified so that the risk of the occurrence of wild strains due to gene recombination is lowered and no virus structural protein is expressed. This vector is highly useful as a gene therapeutic vector with a need for transferring two genes while controlling the expression doses or expression dose ration thereof.

  • Patent number: 6977165
    Abstract: Methods are provided for producing a vector that includes at least one splicable intron. In the subject methods, intron containing vectors are produced from donor and acceptor vectors that each include a site specific recombinase site, where the subject donor and acceptor vectors further include splice donor and acceptor sites that, upon site specific recombination of the donor and acceptor vectors, define an intron in the product vector of the recombination step. Also provided are compositions for use in practicing the subject methods, including the donor and acceptor vectors themselves, as well as systems and kits that include the same. The subject invention finds use in a variety of different applications, including the production of expression vectors that encode C-terminal tagged fusion proteins, the production of expression vectors that encode pure protein and not a fusion thereof, and the like.

  • Patent number: 6974571
    Abstract: Methods of treating patients who are suffering from a disease, disorder or condition characterized by a bone cartilage or lung defect are disclosed. The methods comprising the step of intravenous administration of stromal cells isolated from normal syngeneic individuals or intravenous administration of stromal cells isolated from the patient subsequent to correction of the genetic defect in the isolated cells. Implant devices comprising a container that has at least one membrane surface and stromal cells isolated from bone marrow that comprise a gene construct are disclosed. The gene construct in the stromal cells comprises a nucleotide sequence that encodes a beneficial protein operably linked to regulatory elements which function in stromal cells. Methods of treating individuals with diseases, disorders or conditions which can be treated with a beneficial protein, including diseases, disorders or conditions characterized by gene defects are disclosed.

  • Patent number: 6964861
    Abstract: The present invention relates generally to compositions and methods for enhancing recombinational cloning of nucleic acid molecules. In particular, the invention relates to compositions comprising one or more ribosomal proteins and one or more additional protein components required for recombinational cloning. More particularly, the invention relates to such compositions wherein the ribosomal proteins are one or more E. coli ribosomal proteins, still more particularly wherein the ribosomal proteins are selected from the group of E. coli ribosomal proteins consisting of S10, S14, S15, S16, S17, S18, S19, S20, S21, L20, L21, and L23 through L34, and most particularly S20, L27, and S15. The invention also relates to the use of these compositions in methods for recombinational cloning of nucleic acids, in vitro and in vivo, to provide chimeric DNA molecules that have particular characteristics and/or DNA segments.

  • Patent number: 6962709
    Abstract: The invention provides HSV antigens that are useful for the prevention and treatment of HSV infection. Disclosed herein are epitopes confirmed to be recognized by T-cells derived from herpetic lesions. T-cells having specificity for antigens of the invention have demonstrated cytotoxic activity against cells loaded with virally-encoded peptide epitopes, and in many cases, against cells infected with HSV. The identification of immunogenic antigens responsible for T-cell specificity provides improved anti-viral therapeutic and prophylactic strategies. Compositions containing antigens or polynucleotides encoding antigens of the invention provide effectively targeted vaccines for prevention and treatment of HSV infection.

  • Patent number: 6958237
    Abstract: Highly infectious rubella virus cDNA clones derived from infectious cDNA clone having a low specific infectivity and methods of obtaining highly infectious rubella virus cDNA clones. Togavirus expression vectors of improved stability for the expression of live, attenuated togavirus and a foreign gene, based on the nucleic acid sequence of an infectious rubella virus clone and contain a togavirus non-structural protein open reading frame; an expression element for expression of a foreign gene; a foreign gene or a multiple cloning site for insertion of a foreign gene; an expression element for the expression of the live, attenuated togavirus; and a togavirus structural protein open reading frame. The expression element is either a subgenomic promoter or an internal ribosome entry site (IRES). Administration of the vector as an immunization agents is useful for the induction of immuity against the togavirus, the foreign gene, or both.
