Abstract
To amplify pig interferon-y(pIFN-y) cDNA from ConA-activated peripheral-blood lymphocyte by RT-PCR, then was cloned into pMD18T and sequenced, and recombined with pET32a( + ) vector, the target protein HisX6 IFN-γ was induced by IPTG;the sequence analysis showed that the nucleotide sequences of the IFN-γ in the study shared 98. 6% to 100. 0% homology with that of pig published in GenBank, and the identity of amino acid was 96. 4% to 99. 4%. This recombinant protein , a molecular weight of about 27 ku and mainly presenting in inclusion bodies, was approved to have immunological activity by Western blotting analysis and SDS-PAGE. It laid a foundation for further research of IFN-γ.关键词
