A protocol is described for RNA in situ hybridization using thin sections prepared by Technovit resin. Technovit is a widely used resin for histological examinations. Since it does not require time-consuming processes such as removal of the resin and can be performed without high temperature treatment, a high resolution of sections could be possible compared to other resins and paraffin. Thin sections (approximately 4 μm) were made from inflorescences of Arabidopsis thaliana embedded in Technovit 8100 resin, and in situ hybridization was performed using the protocol described in this article. Hybridization signals were observed using LEAFY and other genes as probes, showing that this resin can be used for in situ analysis. In our experiments, the most important factor for asuccessful in situ hybridization pattern was to optimize the RNase A concentration after hybridization. We routinely used RNase A at a concentration of 2-5 ng/ml, a concentration much lower than that used for paraffin embedding method. Thus, the use of the Technovit resin for plant tissue embedding results in a faster protocol and greater quality than allowed by paraffin sections.
