Blood-borne non-A, non-B hepatitis specific protein, DNA encoding it, and process for its production

摘要

A DNA coding for a blood-borne non-A, non-B hepatitis specific antigenic protein and corresponding to an RNA directly isolated from a human blood or liver tissue is disclosed. This antigenic protein can be produced by using the DNA, and the antigenic protein binds to a antibody in the serum of the patient with the non-A, non-B hepatitis. Therefore, the antigenic protein is useful for the diagnostic measurement of an antibody against the non-A, non-B hepatitis specific antigen.
