A contribution towards making this increasingly valuable technology accessible to researchers, including the students, post-doctoral scholars, and technicians gathering the knowledge inherent in this integration between analysis and physical isolation/purification methodologies. A step-by-step approach to the methodology for measuring various attributes demonstrated in the particular cells of interest is provided, as is a myriad of resources to fuel the curiosity and answer questions of both new and adept users. This book stems from the editors'experiences managing flow cytometry/cell sorting core facilities for the emerging researchers, in particular in developmental, cellular, and molecular biology.
