Abstract: According to swine TIGAR mRNA sequences available in GenBank (No:XM_001926543), a pair of primers was designed, with experimental condition optimizing, the method of a Real-time fluorescent quantitative reverse transcription-polymerase chain reaction (RT-PCR) was established to detect swine TIGAR gene, and the level of TIGAR mRNA of Landrace in different slaughter time was compared with the method established.The results showed that the R2 of standard curves of TIGAR and the housekeeper gene β-actin were 0.9995 and 0.9996, respectively, and the amplification efficiency of TIGAR (103.7%) was consistent with β-actin (104.1%).The methods established can be used for the determination of TIGAR mRNA in swine with high specificity and sensitivity. The research result was valuable to application.
