    • PROBLEM TO BE SOLVED: To provide modified saccharides.SOLUTION: Modified capsular saccharides comprise a blocking group at a hydroxyl group position on at least one of the monosaccharide units of the corresponding native capsular saccharide. The blocking group is formula (Ia) of -O-X-Y or formula (Ib) of -O-R. In the formula, X is C(O), S(O) or SO; Y is NRRor R; Ris a Calkyl group substituted with 1, 2 or 3 groups independently selected from a hydroxyl group, a sulfhydryl group and an amine group; Ris H or a Calkyl group; and Ris a Calkyl group. There are also provided a process for modifying the capsular saccharide with the blocking group, a saccharide-protein conjugate comprising the modified capsular saccharide, a process for making the saccharide-protein conjugate, a pharmaceutical composition comprising the modified capsular saccharide and/or the saccharide-protein conjugate, and a method and use thereof.

    • PROBLEM TO BE SOLVED: To provide a simplified purification procedure which brings about a high purity level while reducing complexity and/or expense of purification steps, and to provide the purification procedure which can obtain a capsular polysaccharide with a good yield regardless of an initial purity of a polysaccharide.SOLUTION: The capsular polysaccharide (cp) is an important immunogen seen on surfaces of bacteria which are participating in various bacterial diseases. According to the feature, the capsular polysaccharide (cp) serves as an important component in the design of a vaccine. If the capsular polysaccharide is particularly connected to a carrier protein, it is shown that the capsular polysaccharide is useful to induce immune response. The present invention relates to the field of bacterial culture, specifically, a novel purification method which is suitable for optimization of culture condition for improving production of bacterial capsular polysaccharide from streptococcus strain in feed batch type cultivation and production scale purification of the bacterial capsule polysaccharide from the streptococcus strain, and which brings about a purity level higher than that obtained on a conventional production scale.
    • 要解决的问题:提供简化的纯化程序,其具有高纯度水平,同时降低纯化步骤的复杂性和/或费用,并且提供可以获得具有良好产率的荚膜多糖的纯化方法,而不管初始纯度如何 的多糖。解决方案:荚膜多糖(cp)是参与各种细菌性疾病的细菌表面上观察到的重要免疫原。 根据该特征,荚膜多糖(cp)是疫苗设计中的重要组成部分。 如果荚膜多糖特别与载体蛋白连接,则显示荚膜多糖可用于诱导免疫应答。 细菌培养领域本发明涉及细菌培养领域,具体而言,适用于优化培养条件,用于改善饲料分批式培养中链球菌菌株的细菌荚膜多糖的生产和细菌胶囊多糖的生产规模纯化 链球菌属菌株,其纯度水平高于常规生产规模获得的纯度。
