GeneratingstablecelllinesinHEK293
Generating stable cell lines in HEK293Prior to transfection, it is recommended that you linearize your pcDNA gene construct. Linearizing will decrease the likelihood of the vector integrating into the genome in a way that disrupts the gene of interest or other elements required for protein expression. Suitable restriction enzymes for linearization are: Bg lII, MfeI, Pvu I, Sca I => for further, check Invitrogen pc......阅读全文

核移植胚胎干细胞的印迹基因甲基化研究
核移植来源的胚胎干细胞(NTES cells)在以干细胞为基础的细胞治疗中扮演着非常重要的角色，得到全能性良好且表观遗传修饰正常的核移植胚胎干细胞是解决治疗性克隆安全问题的重要前提。DNA甲基化修饰在基因表达和印迹基因的表达中起非常重要的作用，两步法克隆可能存在的不完全重编程问题很可能存在于印
