Description
COMPREHENSIVE REFERENCE EXPLORING MICROSCOPY TECHNIQUES TO SUPPORT THE STUDY OF LIVING SYSTEMS WITH A UNIQUE MULTISCALE FOCUS
Live Biological Imaging Across Scales presents an overview of the technologies and experimental strategies available for live imaging across scales. Each chapter highlights a different technique, working upwards from small to large scale. Readers will find critical evaluation of these techniques and perspectives on future developments in this evolving field, enabling them to effectively identify techniques that may benefit their research activities.
Written by a team of leading experts and part of the Wiley-Royal Microscopical Society series, Live Biological Imaging Across Scales includes information on:
- Single cells, covering single molecule tracking/FRET, actin, microtubules, intermediate filaments, septins, vesicles, phagosomes, and confined environments
- Multiple cells, covering collective migration, endothelial monolayers, flow platelets, and flow, wound healing, monocyte transmigration, cancer spheroids/tumor models, and organoids
- Organisms, covering Dictyostelium, C. elegans, Drosophila, and mouse-tumors
- Imaging of whole cells individually and collectively in both 2D and 3D platforms
Live Biological Imaging Across Scales is an essential reference for microscopists and experimental biologists, particularly those interested and/or working in the expanding field of live imaging in biology, as well as those working in the commercial microscopy industry supply and development.
