真核表达质粒pcDNA.3.1(+)-ACE2的构建及其在CHO细胞中的表达
Construction of eukaryotic expression plasmid pcDNA3.1 (+)-ACE2 and its expressions in CHO cells
摘要
Abstract
To construct eukaryotic expression plasmid pcDNA3.1 (+)-ACE2 and observe its expression in CHO,total RNA was extracted from kidney of goat and then ACE2 gene was amplified by reverse transcription polymerase chain reaction (RT-PCR).The product was cloned into pcDNA3.1 (+) vector,and they were identified by PCR and double restrictive edonuclease digestion and sequence analysis.Then the recombinant expression plasmid pcDNA3.1 (+)-ACE2 was transfected into CHO cells by lipofectamine 3 000,and the ACE2 protein expression was identified by Western blot.The results showed that RT-PCR product was around 2 200 bp.Analysis by restricting enzyme digestion and DNA sequencing showed the pcDNA3.1 (+)-ACE2 eukaryotic expression plasmid was successfully established,and the expression of pcDNA3.1 (+)-ACE2 could be detected in CHO cells by western blotting.The pcDNA3.1-CSRP2-HA eukaryotic expression plasmid was constructed successfully,and it could be expressed in CHO cells.This study lays the foundation for the research of the activity and immunological functions of ACE2 protein.关键词
