简介：
Overview
This article presents a protocol for the simultaneous detection of three different genes in brain sections using double fluorescence RNA in situ hybridization combined with immunostaining. This method addresses the challenge of localizing gene expression to specific cell types without the need for specific antibodies.
Key Study Components
Area of Science
