Embodiment 2
[0040] The preparation of kit described in embodiment 1
[0041] (1) The preparation method of the double-labeled enzyme conjugate is: use the improved sodium periodate oxidation method to label horseradish peroxidase on the HCV chimeric antigen, and use the EDC method to label alkaline phosphatase to another HCV For the monoclonal antibody, dilute the chimeric antigen-HRP at 0.1 μg / ml, and HCV mab-ALP at 0.2 μg / ml into the enzyme conjugate diluent containing bovine serum albumin and proclin300, as the enzyme working solution, in 2~ Store at 8°C.
[0042] (2) Negative and positive controls are respectively: use negative mixed human serum as negative control, add HCV-1 antibody in negative serum as positive control 1, add HCV-2 antibody in negative serum as positive control 2, add HCV-2 antibody in negative serum as positive control 2, HCV antigen was added as positive control 3.
[0043](3) The preparation method of the microwell coated plate is: dilute the chimeric antigen ...
