MEANS AND METHODS FOR PRODUCING ARTIFICIAL CAPSULAR POLYSACCHARIDES OF NEISSERIA MENINGITIDIS

摘要

The invention provides for an in vitro method for producing capsular polysaccharides of Neisseria meningitidis. The invention also provides capsular polysaccharides obtainable by the methods described herein. The capsular polysaccharides comprise capsular polysaccharide specific for Neisseria meningitidis serogroups W-135, Y, X and A. Also encompassed are chimeric capsular polysaccharides comprising or composed of CPS of Neisseria meningitidis serogroups Y/W-135, W-135/Y, B/Y, C/Y, B/W-135, C/W-135, B/Y/W-135, C/Y/W-135, B/W-135/Y, C/W-135/Y. X/A or A/X. The invention also provides for the use of these capsular polysaccharides foi as pharmaceuticals, particularly as vaccines and/or diagnostics.
