Microbial Toxins -

. .

Résumé :
Interest in the field of microbial toxins is ever growing and spreading across a broad spectrum of scientific disciplines. In an effort to supplement the available reference texts on toxins, Microbial Toxins: Methods and Protocols includes protocols on mold fungus toxins, with some focus on aflatoxins. Intended to support a wide variety of researchers, Microbial Toxins: Methods and Protocols presents the reader with biological, chemical, physical, and medical approaches, as well as state-of-the-art research techniques. Divided into three convenient sections, this detailed volume covers bacterial protein toxins, endotoxins, and mold fungus toxins. Written in the highly successful Methods in Molecular Biology? series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. ? Authoritative and accessible, Microbial Toxins: Methods and Protocols seeks to serve both professionals and novices with its well-honed methodologies in an effort to further our knowledge of this essential field.
