Lipopolysaccharide Transport, 1st ed. 2022 Methods and Protocols Methods in Molecular Biology Series, Vol. 2548

This volume provides the most widely used protocols and techniques employed in lipopolysaccharide( LPS) transport studies. Chapters detail identification and analysis of essential genes and crucial mutations in LPS transport-related genes, LPS profile determination, LPS chemical analysis, protein-LPS interaction, and LPS visualization. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols.

Authoritative and cutting-edge, Lipopolysaccharide Transport: Methods and Protocols aims to deliver an overview on the multidisciplinary study of LPS transport and to identify new and innovative antibacterial strategies.
