  • Publication number: 20120171241
    Abstract: The invention is based on methods that allow analysis of mixed meningococcal saccharides from multiple serogroups even though they share monosaccharide units. With a combination of saccharides from serogroups C, W135 and Y, the invention analyses sialic acid, glucose and galactose content. The glucose and galactose results are used to directly quantify saccharides from serogroups Y and W135, respectively, and the combined glucose and galactose content is subtracted from the sialic acid content to quantify saccharides from serogroup C. The three serogroups can thus be resolved even though their monosaccharide contents overlap. The three different monosaccharide analyses can be performed on the same material, without interference between the monosaccharides and without interference from any other saccharide materials in the composition (e.g. lyophilisation stabilisers).

  • Patent number: 8133492
    Abstract: This invention provides novel nitrocellulose-based or Hydrogel-based microarrays and methods of making and using them (1) to detect the presence of one or more agents in a sample, (2) to determine the amount of one or more agents in a sample, (3) to determine whether a subject is afflicted with a disorder, and (4) to determine whether an agent known to specifically bind to a first compound also specifically binds to a second compound. This invention also provides kits which comprise the instant microarrays. This invention further provides antibodies capable of specifically binding to a glycomer present both on the surface of a mammalian macrophage or intestinal epithelial cell, and on a bacterial cell. Finally, this invention provides diagnostic methods using the instant antibodies.
