Non-lipidated variants of Neisseria meningitidis ORF2086 antigens

摘要

The present invention relates to compositions including an isolated non- pyruvylated non-lipidated ORF2086 polypeptide, and methods thereof. In an exemplary embodiment, the compositions described herein are immunogenic. The present invention further relates to compositions that elicit a bactericidal immune response in a mammal against an ORF2086 subfamily B polypeptide from serogroup B Neisseria meningitidis, and methods related thereto.
