To exploit recomibinant protein of tiger pufferfish Takifugu rubripes by expression of immune gene and recominant immune factors,the tiger pufferfish interleukin-15(IL15) gene sequence was obtained from kidney tissue by RT-PCR,and the recombinant DNA p ET-32a(+)-IL15 was constructed by link mature peptide gene sequences and prokaryotic expression vector p ET-32a(+).The genetic engineering bacteria of recombinant expression IL15 by transforming p ET-32a(+)-IL15 into Escheria coli BL21(DE3),and the fusion pro...
