Using a collaborative and interdisciplinary author base with experience in the pharmaceutical industry and academia, this book is a practical resource for high content (HC) techniques.
• Instructs readers on the fundamentals of high content screening (HCS) techniques
• Focuses on practical and widely-used techniques like image processing and multiparametric assays
• Breaks down HCS into individual modules for training and connects them at the end
• Includes a tutorial chapter that works through sample HCS assays, glossary, and detailed appendices
