介绍 目录号 Serial | SCSP-223 | 标识符 Identifier | CSTR:19375.09.3101MOUSCSP223 | 描述 Description | R1细胞系建系于1991年8月,取材于两个129亚品系(129S1/SvImJ and 129X1/SvJ)交配获得的3.5天囊胚。R1的多能性最初通过四倍体胚胎检测,当然也可以用二倍体胚胎检测。然而,当进行四倍体聚集体检测时,来自第14代的约20%的亚克隆具有R1的原始发育潜能。R1衍生的动物成年后可育。将经过基因改造的R1细胞注射到C57囊胚中或将其与CD-1或远交系ICR 8细胞期胚胎聚集,可以产生高效的生殖系传递。90%以上敲除克隆通过聚集嵌合体进入生殖系(n> 60)。每个批次均通过本库支原体检测,结果为阴性。冻存时为P22代。 | 动物种别 Organism | 小鼠,129X1×129S1品系 | 性别 Gender | 雄性 | 组织来源 Tissue and Cell Type | 小鼠胚胎内细胞团 | 形态 Morphology | 球形克隆,贴壁生长 | 培养基和添加剂 Complete Growth Medium and Culture Conditions | mES完全培养液配方(600 ml): DMEM (Invitrogen 12430) 497 ml ES级FBS (biochrom S4115) 90 ml Glutamax (Invitrogen 35050) 6 ml NEAA (Invitrogen 11140) 6 ml LIF (Millipore ESG1107) 60 μl(终浓度为1000U/ml) β-Mer (Invitrogen 21985) 1.5 ml 气相:空气,95%;二氧化碳,5%。温度:37摄氏度。 | 供应限制 Permits and Restrictions | A。仅供研究之用。 | REFERENCE | Matise M, et alProduction of targeted embryonic stem cell clonesIn: Matise M, et alGene Targeting: A Practical ApproachOxfordOxford University Press101-132, 1999Nagy A, et al.
