[Abstract]:The MAVS (mitochondrial antiviral signaling protein) gene was amplified and cloned from PK-15 cell line by RT-PCR, and the prokaryotic expression vector p ET-MAVS220, was constructed to transform the receptive cell Rosetta (DE3). The recombinant MAVS was induced by IPTG and immunized with recombinant MAVS for 4 weeks old Kunming mice to prepare polyclonal antibody against mitochondrial antiviral signal protein (MAVS). The best conditions for inducing expression were IPTG 0.05 mmol/L,37 鈩，
