  • Patent number: 6818439
    Abstract: Methods are provided for obtaining measurable levels of a protein, nucleic acid molecule, or enzymatic product in a bodily fluid or cells of a human, comprising the step of administering to a human a recombinant retroviral preparation having a titer on HT1080 cells of greater than 105 cfu/ml, wherein the recombinant retroviral preparation is capable of directing the expression of a protein, nucleic acid molecule, or enzyme which generates an enzymatic product, such that measurable levels of the protein, nucleic acid molecule, or enzymatic product may be obtained in the bodily fluid or cells of the human.
    Type: Grant
    Filed: December 30, 1997
    Date of Patent: November 16, 2004
    Assignee: Chiron Corporation

  • Patent number: 6410316
    Abstract: Retroviral vector particle producing cells are provided, wherein the cell (a) has greater than 5 stably integrated copies of a retroviral vector construct; (b) produces greater than 10 infectious recombinant retroviral vector particles per cell per day; and (c) produces replication incompetent retroviral vector particles.
    Type: Grant

  • Patent number: 6333195
    Abstract: Retroviral vector constructs are described which have a 5′ LTR, a tRNA binding site, a packaging signal, one or more heterologous sequences, an origin of second strand synthesis and a 3′ LTR, wherein the vector construct lacks retroviral gag/pol or env coding sequences. In addition, gag/pol, and env expression cassettes are described wherein the expression cassettes lack a consecutive sequence of more than 8 nucleotides in common. The above-described retroviral vector constructs, gag/pol and env expression cassettes may be utilized to construct producer cell lines which preclude the formation of replication competent virus.
