Abstract:
Over the years, in situ hybridization has been used for visualizing spatial gene expression patterns. Direct comparison of the expression patterns of different genes is useful for studying various biological activities in many situations. If we can distinguish signals derived from different probes in the same hybridization reaction, the localization of multiple gene transcripts can be detected simultaneously. In this chapter, we describe a two-color in situ hybridization procedure, which enables us to compare the expression patterns of two genes in a single tissue section. First, we explain how to prepare RNA probes and tissue samples. Then, we explain how to perform an in situ experiment, including pre-hybridization, hybridization, post-hybridization, and detection steps. A stepwise detection procedure is used to obtain the two color signals.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
