The discovery and genetic engineering of fluorescent proteins has revolutionized cell biology. What was previously invisible in the cell often can be made visible with the use of fluorescent proteins. In Vivo Cellular Imaging Using Fluorescent Proteins: Methods and Prools presents state—of—the—art research that has contributed to the fluorescent protein revolution to visualize biological processes in the live animal. This volume covers an array of topics from the employment of the chick CAM model using fluorescent proteins and other fluorescent probes, to intravital fluorescent imaging, as well as 3—dimensional imaging, and design instructions on how to create new and improved far—red and infrared fluorescent proteins, to name a few. Written in the successful Methods in Molecular Biology™ series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step—by—step, readily reproducible prools, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, In Vivo Cellular Imaging Using Fluorescent Proteins: Methods and Prools is the first volume in the new field of in vivo cell biology and it serves both professionals and novices with its well—honed methodologies.
