This volume introduces different concepts and methods of detecting RNA in biological material in a variety of model systems. The chapters in this book discuss methods that will answer numerous biological questions that arise in the study of RNAs. Some of the topics covered in this book are single mRNA molecule detection in embryos and neurons detection of mRNA and associated molecules by ISH-IEM on frozen sections; optimizing molecular beacons for intracellular analysis of RNA; imaging translation dynamics of single mRNA molecules in live cells; preparation of high-throughput sequencing libraries; and capturing RNA binding proteins in embryos and in cell-culture. Written in the highly successful series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory prools, and tips on troubleshooting and avoiding known pitfalls. Cutting-edge and comprehensive, is a valuable resource for novel and experiences scientist in the expanding field of RNAs.
