This protocol was developed and refined based on standard radioactive and non-radioactive in-situ hybridization methods, previously developed by us and others to detect one or two transcript species in brain tissue 1-7. The protocol described below has a total length of 2 or 3 days, depending on the number of procedural interruptions chosen by the end user. All steps detailed below are to be conducted at room temperature, with the exception of the riboprobe hybridization step and post-hybridization wa...

We have used this protocol to study how the vertebrate brain is neurochemically and functionally organized, and to determine how behaviorally-relevant sensory stimuli impact the genomic machinery of neurons in the adult brain 8-10. We have successfully used this method in brain tissue from mice, rats and songbirds, but anticipate that this protocol will be easily adaptable to brain sections obtained from an array of vertebrate species and, perhaps, non-neural tissues. Key controls required to obtaining reliabl...

double fluorescence in situ hybridization in fresh brain sections

Here we describe a modified version of a double fluorescence in situ hybridization (dFISH) method optimized for detecting two mRNAs of interest in fresh frozen brain sections. Our group has successfully used this approach to study gene co-regulation. More specifically, we have used this dFISH method to explore the anatomical organization, neurochemical properties, and the impact of sensory experience in central sensory circuits, at single cell resolution. This protocol has been validated in brain tissue from mice, rats and songbirds but is expected to be easily adaptable to other vertebrate species, as well as to an array of non-neural tissues. In this film we provide a detailed demonstration of the main steps of this procedure.

Double Fluorescence in situ Hybridization in Fresh Brain Sections

This protocol involves a non-radioactive in-situ hybridization procedure that enables the simultaneous identification of two transcript species, at a single cell resolution, in thin sections of the vertebrate brain.
