SYBR Green I实时荧光定量方法检测结直肠癌患者外周血CEA-mRNA表达研究
Zhongguo shiyan zhenduanxue, 2007 目的建立检测CEA mRNA表达水平的实时荧光定量逆转录聚合酶链反应（FQ-PCR）方法,探讨外周血CEA mRNA表达在结直肠癌患者中的应用价值。方法应用SYBR Green I作为荧光染料,以GAPDH作为内对照,建立检测CEA mRNA的FQ-PCR方法,并对56例结直肠癌患者外周血中CEA mRNA的表达水平进行了检测。结果56例结直肠癌患者中有33例外周血CEA mRNA表达为阳性,表达水平为1.07±2.99,阳性表达率为66.1%（37/56）,30例结直肠良性疾病患者中有2例外周血CEA

Expression of IRG47 and Generation of Rabbit Polyclonal Antibody Against IRG47 [PDF]
, 2015 IRG（Immunity-relatedGTPases）是干扰素γ诱导的免疫相关GTP蛋白，最先在脊椎动物中被发现。IRG蛋白在调节细胞内的病原体先天的抵抗力有着很重要的作用。在动物感染了细菌、原生动物和病毒的时候或者干扰素诱导，IRG蛋白表达量会升高。IRG蛋白在老鼠、兔子、狗、斑马鱼和人中都有表达。其中已经有研究表明，老鼠IRG蛋白在抵抗病原体和细菌作用上起到很重要的作用。IRG47属于IRG蛋白家族成员，但IRG47蛋白的性质和功能还没有被研究。 本文构建了IRG47的表达载体 ...
