Detailed protocols for analyzing DNA strand breaks, specific RNA/DNA expressions, and DNA binding proteins such as transcription factors at the individual cell level. It describes in situ nick translation and TUNEL in detail, along with radioactive and non-radioactive methods for in situ hybridization. Of special significance is the description of Southwestern histochemistry, which makes it possible to analyze the expression of transcription regulatory factors in individual cells. This volume provides an overview of the current status of molecular histochemistry along with practical how-to-do-it details. The methodology is set out in easy-to-follow language by leading scientists working in the field today. Both a rich source of the latest information and a practical lab manual.
