The distribution of the full α-gal epitope (Galα1-3Galβ1-4GlcNAc-R) is unique in mammals, being abundantly expressed on glycoconjugates of non-primate mammals, prosimians and New World monkeys. In contrast, the α-gal epitope is not expressed on glycoconjugates of Old World monkeys, apes and humans; instead, they produce the natural anti-Gal antibody that specifically binds the α-epitope. Anti-Gal mediates the rejection of pig xenograft organs in humans and monkeys by binding α-gal epitopes on the pig cells, inducing complement mediated destruction and antibody dependent cell mediated destruction. This barrier to xenotransplantation has been eliminated by producing α1,3 glycosyltransferase to knockout pigs. Since anti-Gal is ubiquitous in humans, the α-gal epitope has clinical potential in the production of vaccines expressing α-epitopes that can be targeted to antigen presenting cells (APC), thereby increasing the immunogenicity of viral and other microbial vaccines (Macher, 2008).</p>

<p>Tetra-guluronic acid sodium salt (1,4-linked α-L-sodium guluronotetraose) is one of a number of oligosaccharides obtained from alginate, a polysaccharide from brown seaweeds. It contains blocks of: repeating mannuronic acid sequences (M-M-M-M etc), repeating guluronic acid sequences (G-G-G-G etc), and alternating M-G-M-G sequences. This oligosaccharide can be released by acid hydrolysis and a number of biological activities have been discussed in a recent review.</p>

<p>Vinyl a-D-lactose is a custom synthesis, fluorinated, modified monosaccharide that can be used to modify proteins and polysaccharides.
