Methods for Assessing Drug Safety and Toxicity
Redaktion: McGrath, Patricia

• Format: PDF

Produktbeschreibung

Zebrafish: Methods for Assessing Drug Safety and Toxicity offers a practical guide for using zebrafish as a tool for toxicology studies. Consolidating key protocols and approaches to help researchers navigate the important and evolving field of zebrafish models for toxicity screening, this new title describes the methods for using the zebrafish as a model organism to assess compound-induced toxicity on all major organs. Individual chapters that concentrate on assays for each organ system are included and various analytical tools including microscopy, microplate readers, high content imaging systems, ECG, blood pressure monitors, high speed video and motion detectors are described.
