A typical H. pylori O-antigen chain is glycosylated with multiple internal Lex units and possesses either Lex or Ley at the terminal position.
The expression levels of Lewis antigens at pH 7 and pH 5 differed slightly, e.g. in isolates Kx345:4, Kx438 0 and Kx1379 4, which showed reduced expression of Ley at pH 5 as compared to pH 7 (Figure S2).
Lex and Ley are synthesized by the addition of fucose residues to N-acetyl-β-lactosamine (LacNAc) units in the O-antigen chain, which is typically glycosylated with internal Lex units and either Lex or Ley at the terminal position [9].

The passing of the Entrepreneurs' Law (Ley de Emprendedores) comes at a pivotal time for Argentina.
The son of a small landowner, Ley studied at the universities of Jena and Bonn, received a Ph.D. in chemistry, and worked for IG Farbenindustrie, before he was discharged in 1928 for "political activity".
Lewis Y (Ley) is a blood group-related carbohydrate that is expressed at high surface densities on the majority of epithelial carcinomas and is a promising target for antibody-based immunotherapy.
The contractors are working on the space, and at times Mr. Ley can see a fully formed restaurant before his eyes.
