Claims
- 1. Kit for detecting antibodies to HCV comprising:at least one of an E1 protein and an E2 protein, said E1 protein and E2 protein having been purified to at least 80% pure; and a buffer or components necessary for producing a buffer enabling formation of an immune complex between said protein and at least one of an anti-E1 antibody or anti-E2 antibody present in a biological sample, and optionally, means for detecting said immune complex, and optionally, at least one of an automated scanning or interpretation device for inferring a decrease of said anti-E1 antibody or anti-E2 antibody titers.
- 2. The kit according to claim 1 wherein said at least one protein is an E1 protein.
- 3. The kit according to claim 1 wherein said at least one protein is an E2 protein.
- 4. The kit according to claim 1, wherein said at least one protein is a purified recombinant HCV single or a specific oligomeric recombinant envelope protein selected from the group consisting of an E1 protein which has been purified to at least 80% pure and an E2 protein which has been purified to at least 80% pure.
- 5. The kit according to claim 4 wherein said recombinant protein had been expressed in recombinant mammalian cells.
- 6. The kit according to claim 4 wherein said recombinant protein had been expressed in recombinant yeast cells.
- 7. A kit according to claim 1 wherein said biological sample has been obtained from a patient receiving interferon.
- 8. A method for detecting antibodies to HCV comprising:combining a sample which may contain said antibodies with at least one of an E1 protein of HCV which had been purified to at least 80% pure and an E2 protein of HCV which had been purified to at least 80% pure, and a buffer, under conditions such that an immune complex between said at least one protein and said antibodies present in said sample is formed; and detecting said immune complex.
- 9. The method according to claim 8 wherein said at least one protein is an E1 protein.
- 10. The method according to claim 8 wherein said at least one protein is an E2 protein.
- 11. The method according to claim 8 wherein said at least one protein is a recombinant HCV single or a specific oligomeric recombinant envelope protein selected from the group consisting of an E1 protein which had been purified to at least 80% pure and an E2 protein which had been purified to at least 80% pure.
- 12. The method according to claim 11 wherein said recombinant protein had been expressed in recombinant mammalian cells.
- 13. The method according to claim 11 wherein said recombinant protein had been expressed in recombinant yeast cells.
- 14. The method according to claim 8 wherein said sample had been obtained from a patient receiving interferon.
- 15. Kit for detecting antibodies to HCV comprising an E1 protein of HCV and an E2 protein of HCV wherein at least one of said E1 protein and E2 protein has been purified to at least 80% pure; anda buffer or components necessary for producing a buffer enabling formation of an immune complex between said protein and at least one of an anti-E1 antibody or anti-E2 antibody present in a biological sample, and optionally, means for detecting said immune complex, and optionally, at least one of an automated scanning or interpretation device for inferring a decrease of said anti-E1 antibody or anti-E2 antibody titers.
- 16. The kit according to claim 15 wherein each of said E1 protein and said E2 protein have been purified to at least 80% pure.
- 17. The kit according to claim 15 wherein at least one of said E1 protein of HCV and E2 protein of HCV is a purified recombinant HCV single or a specific oligomeric recombinant envelope protein which had been purified to at least 80% pure.
- 18. The kit according to claim 17 wherein said recombinant protein had been expressed in recombinant mammalian cells or recombinant yeast cells.
- 19. A method for detecting antibodies to HCV comprising:combining a sample which may contain said antibodies with an E1 protein of HCV and an E2 protein of HCV wherein at least one of said E1 protein and said E2 protein has been purified to at least 80% pure, and a buffer, under conditions such that an immune complex is formed between said antibodies present in said sample and at least one of said E1 protein and said E2 protein; and detecting said immune complex.
- 20. The method of claim 19 wherein each of said E1 protein and said E2 protein have been purified to at least 80% pure.
- 21. The method of claim 19 wherein at least one of said E1 protein of HCV and E2 protein of HCV is a purified recombinant HCV single or a specific oligomeric recombinant envelope protein which had been purified to at least 80% pure.
- 22. The method of claim 22 wherein said recombinant protein had been expressed in recombinant mammalian cells or recombinant yeast cells.
