牛胰岛素,是一种多肽
在1965年9月17日我国完成了结晶牛胰岛素的全合成。经过严格鉴定,它的结构、生物活力、物理化学性质、结晶形状都和天然的牛胰岛素完全一样。这是世界上第一个人工合成的蛋白质,为人类认识生命、揭开生命奥秘迈出了可喜的一大步。这项成果获1982年中国自然科学一等奖。
1953年,英国人F. SangerSanger由于测定了牛胰岛素的一级结构而获得1958年诺贝尔化学奖。
我用Promega公司的双荧光素酶检测试剂盒(E2920)检测到的firefly萤光素酶活性很低,只有4*10的3次方;海肾萤光素酶活性有10的6次方。
我用Ad293细胞做了转染,fireflyluciferase质粒:RanillaLuciferase质粒=0.1ug:0.025ug/一个孔(96孔板),共转染了二天,再进行双萤光素酶检测。
我想了解fireflyluciferase活性用promega的这个E2920-双萤光素酶试剂盒检测得到10的3次方,这种数值正常吗?
我做了3次重复实验,每次firefly萤光素酶活性很低,只有4*10的3次方;而海肾萤光素酶活性有10的6次方。
求指教?fireflyluciferase活性低?会是什么原因呢?
实验室要开展支原体检测,方法是PCR法,先要采购试剂盒,用过的同学给推荐一下好用的品牌呗
