In Situ Hybridization Using Oligonucleotide Probes to Study RNA Expression in Rat Brain Sections

Source: Shokry, I. M., et al. Rapid In Situ Hybridization using Oligonucleotide Probes on Paraformaldehyde-prefixed Brain of Rats with Serotonin Syndrome. J. Vis. Exp. (2015). This video demonstrates the detection of serotonin receptor RNA synthesis using oligonucleotide probes in rat brain tissue affected by serotonin syndrome. The protocol includes tissue pretreatment, probe hybridization, and enzymatic detection to visualize and quantify serotonin receptor RNA expression under a microscope.
