摘要: 为了建立稳定表达猪FcγRⅢ(PorcineFcgammareceptorⅢ,poFcγRⅢ)的Marc-145细胞系,从PAM细胞中提取总RNA,应用RT-PCR技术获得猪FcγRⅢ和γ链的cDNA,并构建PIREShyg3-γ和pcDNA3.1-FcγRⅢ真核表达质粒;用脂质体共转染Marc-145细胞,经潮霉素B(300mg/L)和G418(400mg/L)共筛选获得稳定表达猪FcγRⅢ的细胞系;运用RT-PCR、玫瑰花环试验和流式细胞术对细胞系进行了鉴定。结果表明,成功构建了猪FcγRⅢ和γ链真核表达载体,建立了稳定表达猪FcγRⅢ的细胞系,表达于转染细胞表面的猪FcγRⅢ受体分子能与猪IgG特异结合。

Abstract: The objective of the present study is to establish the Mare 45 cell line that stably expresses porcinepo.The total RNA was extracted from porcine alveolar macro-phage (PAM),they were inserted into the eukaryot-is expression vectors.The expression of poFcyRIII on transfected cells was verifiedthrough RTCR resetting test and FCM.The eukaryotic expression vectors were successfully constructed .

Key words: poFcyR receptor, y chain, Coransfection, Marc45 cell line
