Preparation of Lipooligosaccharide (LOS) from Neisseria gonorrhoeae

Neisseria gonorrhoeae is a gram-negative obligate human pathogen that contains lipooligosaccharide (LOS) as a major constituent within the outer membrane. LOS plays a major role in pathogenesis by inducing host inflammatory responses and also enabling evasion of host innate immunity through sialylation. Epitopes within LOS are also potential vaccine candidates. In this chapter, we describe a general method based on the Westphal hot phenol extraction process to purify whole LOS from N. gonorrhoeae for structural analyses and for use in in vivo and in vitro biological assays.

Abstract

Neisseria gonorrhoeae is a gram-negative obligate human pathogen that contains lipooligosaccharide (LOS) as a major constituent within the outer membrane. LOS plays a major role in pathogenesis by inducing host inflammatory responses and also enabling evasion of host innate immunity through sialylation. Epitopes within LOS are also potential vaccine candidates. In this chapter, we describe a general method based on the Westphal hot phenol extraction process to purify whole LOS from N. gonorrhoeae for structural analyses and for use in in vivo and in vitro biological assays.
