| Abstract: | 【Objective】To clone and construct the eukaryotic expression vector containing the bovine follistatin cDNA sequence.【Methods】Total RNA was extracted from bovine ovary by Trizol total RNA Extract Kit,and the whole coding region of bovine follistatin cDNA gene was cloned by RT-PCR using specific primers containing restriction enzyme cutting site.The purified bovine follistatin cDNA was inserted into pMD18-T vector and was then sequenced,then subclone the correct follistatin cDNA to eukaryotic expression vector pIRES-AcGFP.Double-enzyme cleavage and PCR test were used to identify the vector.【Results】Double-enzyme cleavage and PCR test showed that FSTN was successfully cloned into eukaryotic expression vector.【Conclusion】We successfully constructed the eukaryotic expression vector pIRES2-AcGFP1-FSTN.This study provided the foundation for fostering high beef quality transgenic cattle of promoting muscle growth. |
