Protocol for Single-Molecule Fluorescence In Situ Hybridization for Intact Pancreatic Tissue

STAR Protoc. 2020 Jun 3;1(1):100007. doi: 10.1016/j.xpro.2019.100007. eCollection 2020 Jun 19.

Abstract

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.
