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.
Synthesis and 13C-NMR spectroscopic investigations of rhamnobioses
for the synthesis of all mono- and di-O-benzyl ethers of methyl α-L-rhamnopyranoside applying a new stereoselective method for the hydrogenolytic ring-cleavage of benzylidene acetals. Using the prepared dibenzyl ethers as aglycones, the (1→2)-, (1→3)- and (l→4)-linked rhamnosyl-rhamnose derivatives (13–15) were synthesised. Hydrogenolysis of the latter compounds and subsequent acetylation gave the
