We describe an optimized smFISH protocol for the intact pancreas. The protocol is adapted from Lyubimova et al. (2013), a generic tissue smFISH protocol that works for most tissues but not the pancreas. The main changes implemented include increasing the period of mRNA denaturation from 5 min to at least 3 h and increasing formamide concentrations from 10% to 30%. These modifications yield sensitive single mRNA visualization that is comparable to those achieved in other tissues using the standard protocol. For complete details on the use and execution of this protocol, please refer to Farack et al., 2018, Farack et al., 2019.
我们描述了一种优化的 smFISH 方案用于完整的胰腺。该方案改编自 Lyubimova 等人(2013 年)的方案,这是一种通用的组织 smFISH 方案,适用于大多数组织,但不适用于胰腺。实施的主要改动包括将 mRNA 变性的时间从 5 分钟增加到至少 3 小时,并将甲酰胺浓度从 10%增加到 30%。这些修改产生了敏感的单个 mRNA 可视化效果,与使用标准方案在其他组织中获得的效果相当。有关该方案使用和执行的完整详细信息,请参考 Farack 等人,2018 年,Farack 等人,2019 年。
