ABSTRACT
Objective:
To obtain eukaryotic expressing protein of chicken interferon ? (ChIFN-?) and research its anti-virus activity.Methods:
Chicken interferon ? mature protein gene was cloned and amplified by reverse transcripition-polymerase chain reaction(RT-PCR) from the total mRNA in the lymphocyte of chicken blood stimulated with ConA for 4~10 hours.The gene was inserted into the expression vector pPICZa-A,which had been cleaved by EcoR I and Xba I.The recombinant vector was linearized by Sac I and transferred into yeast Pichia pastoris,strain X33,anti-virus activity of the recombinant cytokine was detected by the classical experiment cell pathological effect inhibition assay.Results:
The result showed that the preparation of recombinant interferon had higher anti-virus activity(10?48 U/ml).Conclusion:
The recombinant chicken interferon ? with anti-virus bioactivity has been obtained.
