Human interferon analogue with long-lasting biological effects

The invention relates to human interferon analogue with long-lasting biological effects and preparation method and medicinal effect thereof. The human interferon analogue is a syzygial albumin prepared by recombination of interferon and human serum albumin (HSA) in gene engineering method. Proved by animal experiment, the novel interferon has not only anti-virus effect of general interferon but also has prolonged half time as 3 to 10 times as other interferon, therefore, internal action time is prolonged. The long-lasting interferon can be used for treating virulence infection diseases, such as SARS, AIDS, hepatitis b, hepatitis c and hepatitis a, and can also be used for treating leukemia and chromoma.
