  • Publication number: 20180136233
    Abstract: The present invention provides antibodies and methods for preparing antibodies to metabolites in the serotonin, tryptophan, kynurenine pathways. The prepared antibodies have low cross-reactivity to related metabolites, and are useful reagents for specific and sensitive immunoassays The present invention also provides stable derivatives of various metabolites and short chain fatty acids. The derivative can be conjugated to a biomolecule such as a carrier protein and combined with an adjuvant to stimulate an immune response. The derivatives can also be conjugated to other biomolecules.

  • Publication number: 20170240652
    Abstract: The present invention provides antibodies and methods for preparing antibodies to metabolites in the serotonin, tryptophan and kynurenine pathways, such as 5-hydroxyindole-3-acetic acid (5-HIAA), melatonin (MT) and kynurenic acid (KYNA). The specific metabolite antibodies have low cross-reactivity to structurally related metabolites, and are useful reagents for specific and sensitive immunoassays. The present invention also provides methods for using such antibodies to measure the levels of 5-HIAA, melatonin, or kynurenic acid in biological samples from human patients.

  • Patent number: 9512482
    Abstract: The present invention provides compositions, methods, and kits for discriminating sequence variation between different alleles. More specifically, in some embodiments, the present invention provides compositions, methods, and kits for determining the presence and/or level (e.g., quantitating) of rare (e.g., mutant) allelic variants, such as single nucleotide polymorphisms (SNPs) or nucleotide insertions or deletions, in samples comprising abundant (e.g., wild-type) allelic variants with high sensitivity and/or specificity. As such, in certain embodiments, the present invention provides a highly selective method for the detection of somatic mutations, e.g., in samples containing abundant levels of a wild-type allele compared to very low levels of a mutant allele.

  • Publication number: 20150072879
    Abstract: The present invention provides methods and systems to predict and diagnose inflammatory bowel disease (IBD) and subtypes such as ulcerative colitis (UC) and Crohn's disease (CD) by detecting the presence, absence, level, and/or genotype of one or more sero-genetic-inflammation markers. Advantageously, with the present invention, it is possible to provide a diagnosis of IBD versus non-IBD, to rule out IBD that is inconclusive for CD and UC, and to differentiate between CD and UC with increased accuracy.

  • Publication number: 20140179549
    Abstract: The present invention provides methods for identifying IBD patients with dysplasia or cancer. In particular embodiments, the methods of the invention may comprise determining the presence or level of at least one or a panel of miRNAs in a sample obtained from an IBD patient to establish a miRNA expression profile, and comparing the miRNA expression profile with one or more pre-established model miRNA expression profiles. The present invention further provides methods for monitoring the efficacy of treatment of IBD patients with dysplasia or cancer.
