  • Patent number: 9541558
    Abstract: A cysteine hydrazide nicotinamide (Cyhn) reagent designed for the enrichment of bacterial glycoproteins is provided. Methods for purification of free oligosaccharides and their analysis are also provided.
    Type: Grant
    Filed: September 4, 2013
    Date of Patent: January 10, 2017
    Assignee: California Institute of Technology

  • Patent number: 8852891
    Abstract: The present invention relates to a novel N-acetylglucosamine-2-epimerase and a method for preparing CMP-N-acetylneuraminic acid, more specifically, relates to a N-acetylglucosamine-2-epimerase derived from Bacteroides fragilis NCTC 9343, and a method for preparing CMP-N-acetylneuraminic acid using said N-acetylglucosamine-2-epimerase. According to the present invention, CMP-N-acetylneuraminic acid can be produced economically in a large amount through a one-step reaction using cytidine monophosphate and N-acetyl-D-glucosamine which are inexpensive substrates.

  • Publication number: 20120190634
    Abstract: A lipoteichoic acid (LTA)-derived glycolipid, and a pharmaceutical, food or cosmetic composition and a vaccine adjuvant including the same are provided. The LTA-derived glycolipid can inhibit the production of inflammatory cytokines and thus have anti-inflammatory effects. Therefore, the pharmaceutical, food or cosmetic compositions including the LTA-derived glycolipid can be used to prevent and treat inflammatory diseases, and the LTA-derived glycolipid can be also used as the vaccine adjuvant.
