The conserved surface polysaccharide poly-β-(1,6)-N-acetyl-D-glucosamine (PNAG) is a promising vaccine target but antibodies raised against PNAG have shown restricted efficacy. Here, the authors describe an effective n + 2 glycosylation strategy, with control over the degree of N-acetylation, that allows the iterative assembly of partially and fully deacetylated PNAG glycans and investigate their potential as vaccine candidates.
