单细胞多重 rt-pcr 后贴片钳可以同时可靠地探测30多个基因在 electrophysiologically 识别细胞5的表达。在单细胞水平上分析基因表达需要高效的 PCR 引物。最限制的步骤之一是单元格内容的集合。其效率取决于贴片吸管尖端的直径, 它必须尽可能大, 同时匹配的细胞大小。吸管与1-2 µm 开尖直径被证明是适合大多数神经元类型。同样重要的是要确保只收集细胞的内容, 而不是周围的组织?...

大脑皮层包括多种细胞类型, 涉及各种生理过程。考虑到皮层细胞类型的形态学、生理和分子多样性, 它们的识别和表征是理解其特定功能的先决条件, 这是非常有挑战性的.1 ,2,3,4。
单细胞复合 rt-pcr 是基于膜片钳和 rt-pcr 技术相结合的。它可以同时探测30多个预定义基因在 electrophysiologically 识别细胞5中的表达。在记录吸管中加入神经元示踪剂进一步允许在组织化学揭示6、7、8、9后, 记录细胞的形态学特征,10. 基于对其表型性状5、9、10、11、12 的多元分析, 这是一种非常有用的神经类型分类方法. ,13,14。单细胞多重 rt-pcr 也适合于非神经细胞的特征, 如星形胶质细胞15,16,17, 几乎可以应用到每一个大脑结构18, 19、20、21、22、23和单元格类型, 假设它们可以在全单元格配置中进行记录。
这项技术是非常方便的识别细胞源和/或目标的传输系统7,8,15,16,20,21, 24,25,26,27,28, 特别是缺乏特定抗体时。它依赖于从视觉上识别出的细胞29的补丁钳录音, 因此也允许在特定的蜂窝环境8,15,16中定位细胞。此外, 由于大脑组织的细胞构筑被保存在脑切片中, 这种方法还可以研究具有神经元和非神经元元素的特征细胞的解剖关系7,8,18。
由于该技术受所收获细胞质数量和 RT 效率的限制, 在低拷贝数的情况下检测 mRNA 可能很难。虽然基于 RNaseq 技术的其他方法允许分析单个单元3、4、30、31的整个转录, 但它们需要高吞吐量的昂贵音序器不一定每个实验室都可以使用。由于单细胞复用 rt-pcr 技术采用终点 pcr 方法, 因此只需要广泛使用 thermocyclers。它可以很容易地开发在装有电生理设置的实验室, 不需要昂贵的设备。它可以在一天内提供一组预定义基因的定性分析。因此, 这种方法可以很容易地获得单个细胞的分子特征。
