产品信息
EnGen® Lba Cas12a 核酸酶来自毛螺菌科细菌 ND2006(Lachnospiraceae bacterium ND2006),是一种位点特异性 DNA 核酸内切酶,由长度为 41-44 个核苷酸的单向导 RNA(gRNA)介导识别(1)。靶向识别需要一段与目标位点互补的 gRNA,以及位于目标序列对侧的 DNA 链上的 5’ TTTV PAM(Protospacer Adjacent Motif)序列。EnGen Lba Cas12a 核酸酶的切割位点位于 PAM 序列 3´ 端约第 18 个碱基处,切割产物为 5´ 突出末端。EnGen Lba Cas12a 核酸酶蛋白的 N 端和 C 端都含有猴病毒 40(SV40)T 抗原核定位序列(NLS)。
产品来源
EnGen Lba Cas12a 核酸酶,克隆自毛螺菌科细菌 ND2006(Lachnospiraceae bacterium ND2006),在大肠杆菌中表达,为 N 端含 6xHis 标签的融合蛋白。
