This authoritative volume examines immunohishemical methods aimed at investigating the toxicologic pathology of rodent, non-human primate and aquatic animal tissues. Eleven comprehensive chapters provide pathologists and researchers in various sub-disciplines of toxicology with a comprehensive review of the methods and approaches for immunohishemical staining in various target tissues. It explores the tissue-antigen and antibody-specific problems that may be encountered during the staining procedures and provide potential avenues for resolving various methodological issues. Special attention is paid to the latest enhancement procedures for antigen retrieval and visualization as well as image analysis and antigen quantification. Written by leading researchers in toxicology and pathology, this book is a significant resource for toxicologists and pathologists working with rodents, monkeys and aquatic animal tissues.
