Author(s): 
Pages: 238-240
Year: Issue:  3
Journal: JOURNAL OF SHANGDONG UNIVERSITY(HEALTH SCIENCES)

Keyword:  LTC4合酶靶向载体基因敲除;
Abstract: 目的:构建鼠LTC4合酶基因靶向敲除载体,用于转染鼠胚胎干细胞,建立LTC4合酶基因敲除鼠.方法:分离、克隆LTC4合酶基因的1.85kb和1.35kb片段,作为靶向载体的5'同源臂和3'同源臂,重组到pJNS2载体中,筛选鉴定阳性重组子.结果:构建的靶向载体由5'同源臂-Neo-3'同源臂-hTk-pJNS2构成.结论:经DNA测序及限制性酶切鉴定分析,该构建载体结构及序列正确,可用于转化鼠胚胎干细胞.
