The known methyl 2-O-acetyl-3,4-di-O-benzyl-1-thio-alpha-L-rhamnopyranoside (3) was converted to the corresponding 5-methoxycarbonylpentyl glycoside 4 which was deacetylated. The product 5 was used as the initial glycosyl acceptor to construct two trirhamnoside glycosyl acceptors having HO-3(III) flanked by either benzoyl or benzyl groups, compounds 10 and 29, respectively [fullyprotected, except HO-3(III)
Immunoadsorbent combinations for the detection and diagnosis of group B streptococcus polysaccharide antigen, comprising an insoluble carrier, a capture agent having an affinity for specifically binding to the trirhamnose epitope of group B streptococcus antigen and having the formula α-L-Rhap(1->2)-α-L-Rhap(1->2)α-Rhap-1- wherein Rhap is rhamnose, and an antigen marker agent having an affinity for binding to monorhamnose epitope of group B streptococcus polysaccharide antigen of formula α-L-Rhap-1- when the group B streptococcus polysaccharide is bound to the carrier. An immunoassay method test kit and polyclonal antibody are also described.

The invention relates to novel photo-generated carbohydrate arrays and methods of their use to detect the presence of one or more agents in a sample. The invention also relates to a high-throughput strategy to facilitate the identification and immunological characterization of pathogen-specific carbohydrates, including those of
Bacillus anthracis
. The invention can be used to determine the presence of a pathogen and whether a subject has been exposed to a pathogen, such as by screening for pathogen-specific antibodies.

This invention provides a vaccine comprising (i) an anthrose-containing saccharide in an amount effective to enhance immunity against
Bacillus anthracis
in a subject and (ii) a pharmaceutically acceptable carrier. This invention provides a vaccine comprising (i) a conjugate of an anthrose-containing saccharide in an amount effective to enhance immunity against
Bacillus anthracis
in a subject, wherein the anthrose-containing saccharide is conjugated to a biomolecule via a linker, and (ii) a pharmaceutically acceptable carrier. This invention provides a method for vaccinating a subject against
Bacillus anthracis
infection comprising administering to the subject a vaccine comprising (i) an anthrose-containing saccharide in an amount effective to enhance immunity against
Bacillus anthracis
in the subject and (ii) a pharmaceutically acceptable carrier, in an amount effective to stimulate production of antibodies to
Bacillus anthracis
spores in the subject, thereby vaccinating the subject against
Bacillus anthracis.
