摘要 目的:建立稳定表达人FcγRⅡ(human Fc gamma receptor Ⅱ,huFcγRⅡ)的真核细胞系,为后续研究奠定基础。方法:采用RT-PCR方法从人外周血白细胞合成FcγRⅡcDNA,构建huFcγRⅡ表达质粒pcDNA3-huFcγRⅡ,经酶切和PCR鉴定后,将pcDNA3-huFcγRⅡ质粒通过脂质体转染法转染COS7细胞,并经G418筛选获得稳定表达huFcγRⅡ的细胞克隆。采用免疫荧光法和玫瑰花环试验检测huFcγRⅡ的表达。结果:构建的pcDNA3-huFcγRⅡ真核表达质粒经酶切鉴定与预期一致,稳定转入COS7细胞后,经免疫荧光染色,约90%的转染细胞可见荧光,而未转染的COS7对照细胞未见荧光。结论:成功构建pcDNA3-huFcγRⅡ真核表达质粒,建立了稳定表达huFcγRⅡ的细胞系,为进一步研究奠定了基础。
