pBluescript II KS(+)载体简介
pBluescript II-KS(+)是大肠杆菌原核质粒。为克隆载体，其来源于噬菌体。该载体常被用在克隆和测序过程中，包括DNA测序中，嵌套缺失的构建；体外RNA转录，定点突变和基因定位。pBluescript II-KS(+)带有21个独特限制性内切酶的识别位点。在MCS区两侧是T7和T3 RNA聚合酶启动子序列，其主要帮助RNA的体外合成。pBluescript II SK(+)和 pBluescript II KS(+) 差异仅仅存在于多克隆位点的方向不同。 Standard cloning vector (phagemid excised from lambda ZAPII). The f1 (+) orientation allows rescue of sense strand ssDNA. pBluescript II KS(+) and pBluescript II SK(+) differ by the orientation of the MCS.
