工具鼠

赛业生物可为您提供Cre工具鼠、诱导型Cre工具鼠、荧光标记模型、Dre工具鼠、线粒体工具鼠、离子通道工具鼠等,可实现多组织多器官的重组酶活性验证。

Cre工具鼠

Cre‑LoxP重组系统是动物体内条件基因操作的主流技术体系。Cre工具鼠通过启动子调控实现Cre重组酶的时空特异性表达,可精准限定基因修饰发生的组织、细胞类型与时间节点,有效规避全身性基因修饰导致的早期发育缺陷,在基因功能解析、细胞谱系追踪、组织特异性疾病动物模型构建中发挥关键作用。赛业生物可为您提供Cre工具鼠、诱导型Cre工具鼠、荧光标记模型、Dre工具鼠、线粒体工具鼠、离子通道工具鼠等,可实现多组织多器官的重组酶活性验证。

如何选择合适的Cre工具鼠?

在进行实验设计时,首先需要明确实验的目的是需要组织特异性或是药物诱导类型的Cre工具鼠,然后根据启动子、LoxP位点插入位置、遗传背景等因素综合考虑,以确保实验设计的准确性和有效性。

  • 分析小鼠构建方式:启动子的选择直接影响Cre重组酶的表达特异性和效率,需要确定所选启动子在体内的表达范围与实验需求相符。LoxP位点的插入位置和连接方式关系到工具鼠的表达量及重组难度,同样需要关注。
  • 考虑打靶背景:不同遗传背景的Cre工具鼠在功能上可能存在差异,甚至在同一品系的不同亚系之间也可能有显著差异。flox鼠与Cre鼠配对繁殖后可能会产生杂合背景,因此也需要确保flox鼠的遗传背景与Cre鼠兼容,以避免不必要的基因背景干扰。
  • 胚胎致死性基因的考虑:部分关键基因敲除后可能会导致胚胎致死性或功能缺失。因此在实验设计前需要查阅相关文献,了解目标基因的功能和敲除后可能的表型。
  • 选择了诱导性工具鼠,实验难度会增加,因为涉及到他莫昔芬诱导过程。需要考虑药物注射方法、剂量和诱导时间等。
