TLR22 gene in common carp is a member of the Toll-like receptor family, which is involved in the immune response of common carp. The aim of this study is to study the molecular cloning and function of TLR22 gene in common carp, and to provide new theoretical basis for the research of common carp immune mechanism.In this study, reverse transcription PCR method will be used to design specific primers based on the existing sequence of common carp TLR22 gene. The full-length sequence of common carp TLR22 gene will be obtained through PCR amplification, and the recombinant plasmid will be constructed and transformed into Escherichia coli. The recombinant protein sample will be obtained by protein expression and purification technology. The recombinant protein will be identified and confirmed by western blotting and mass spectrometry analysis. Further cell experiments will be performed to 精品文档---下载后可任意编辑investigate the function of common carp TLR22 gene in immune response.The expected results are to successfully clone common carp TLR22 gene and confirm its expression and purification products. At the same time, the role of common carp TLR22 gene in cell immune response will be studied, which will provide a new theoretical basis for the research of common carp immune mechanism.【Keywords】Common carp, TLR22 gene, molecular cloning, immune mechanism.
