Current Protocols in Toxicology, a member of the noted Current Protocols series of manuals, provides detailed, step-by-step protocols for both new and experienced investigators. The scope ranges from specific systems (immune, neural, behavioral, hepatic, reproductive) to processes (cell toxicity, mutagenesis, biotransformation, toxicokinetics, oxidative stress), to specific molecules (glutathione, heme. nitric oxide). CP in Toxicology is updated quarterly.
