鹅IL-2成熟基因的表达及重组蛋白生物活性检测
Chinese Journal of Preventive Veterinary Medicine（2009）
Abstract
从PHA活化的东北白鹅外周血淋巴细胞中分离提取总RNA,利用反转录PCR技术扩增获得鹅IL-2(GoIL-2)基因,连接至克隆载体后进行测序鉴定,结果与预期大小一致.将去除信号肽的成熟基因亚克隆至原核表达载体,构建原核重组表达质粒并转化至大肠杆菌中进行诱导表达,用表达纯化的融合蛋白制备多克隆抗血清.此外,体外淋巴细胞增殖实验结果显示,鹅GoIL-2重组蛋白具有促进淋巴细胞增殖的活性,这为进一步研究GoIL-2的功能奠定了基础.
