  • Patent number: 6861212
    Abstract: A family of cDNA sequences derived from hepatitis C virus (HCV) are provided. These sequences encode antigens which react immunologically with antibodies present in individuals with non-A non-B hepatitis (NANBH), but which are absent from individuals infected with hepatitis A virus, or hepatitis B virus, and also are absent in control individuals. The HCV cDNA sequences lack substantial homology to the sequences of hepatitis delta virus (HDV) and HBV. A comparison of the sequences of amino acids encoded in the HCV cDNA with the sequences of Flaviviruses indicates that HCV may be related to the Flaviviruses. The HCV cDNA sequences and the polypeptides encoded therein are useful as reagents for the detection and therapy of HCV. The reagents provided in the invention are also useful for the isolation of NANBH agent(s), for the propagation of these agents in tissue culture, and for the screening of antiviral agents for HCV.

  • Publication number: 20050037475
    Abstract: Highly purified preparations of TFPI or TFPI analogs can be prepared using a method that generally involves the following steps: (1) expression of TFPI or TFPI analog in E. coli, (2) isolation of refractile bodies, (3) dissolution of the refractile bodies and refolding of the expressed TFPI or TFPI analog, (4) SP-Sepharose fast flow (FF) chromatography, (5) a first concentration and diafiltration step, (6) Q-Sepharose high (HP) performance chromatography, (7) butyl hydrophobic interaction chromatography (HIC), (8) SP-Sepharose HP chromatography, and (9) a second concentration/diafiltration step. Less than about 12% of the TFPI or TFPI analog molecules in such preparations are modified TFPI or TFPI analog species (i.e., oxidized, carbamylated, acetylated, deamidated, aggregated, or misfolded species).

  • Patent number: 6855549
    Abstract: The present invention involves methods and compositions for increasing the susceptibility of target cells to transduction by gene transfer vectors. Specifically, it is proposed that increasing intracellular permeability in epithelial tissue increases the percentage of input vector that will transduce that target tissue. Specific examples show that receptors for retrovirus are preferentially accessible on the basolateral surface of airway epithelia, and permeabilizing such tissues results in greater infection with retrovirus. This has important implications in gene therapy, for example, to treat cystic fibrosis with the CFTR gene.

  • Patent number: 6846921
    Abstract: Chimeric oligonucleotide of the formula 5?-W—X1—Y—X2—Z-3?, where W represents a 5?-O-alkyl nucleotide, each of X1 and X2 represents a block of seven to twelve phosphodiester-linked 2?-O-alkyl ribonucleotides, Y represents a block of five to twelve phosphorothioate-linked deoxyribonucleotides, and Z represents a blocking group effective to block nuclease activity at the 3? end of the oligonucleotide, are described. These compounds exhibit high resistance to endo- and exonucleases, high sequence specificity, and the ability to activate RNAse H, as evidenced by efficient and long-lasting suppression of target mRNA. The oligonucleotides are preferably transfected into cells in formulations containing a lipid-peptoid conjugate carrier molecule of the formula L-linker-[N(CH2CH2NH2)CH2(C?O)—N(CH2CH2R)CH2(C?O)—N(CH2CH2R)CH2(C?O)]3—NH2, where L is a lipid moiety, including a steroid, and each group R is independently selected from alkyl, aminoalkyl, and aralkyl.
