  • METHOD OF PURIFYING POLYSACCHARIDES
    Publication number: 20220411540
    Abstract: The present disclosure provides a method of purifying polysaccharides from a cell lysate, comprising partially purifying the cell lysate comprising an impurity and a polysaccharide to obtain a clarified cmde lysate; mixing the clarified crude lysate with a neutralization solution comprising a salt to form a neutralized lysate; mixing the neutralized lysate with a precipitation solution comprising cetyltrimethylammonium bromide to form a first supernatant and a first precipitate; and separating the first precipitate from the first supernatant, wherein the polysaccharide is located in the first supernatant. The present disclosure further provides a method of making a polysaccharide vaccine. Also provided are vaccines, delivery systems, compositions and polysaccharides made by the methods described herein.

  • Purification Process for Biological Molecules Such as Plasmid DNA Using Anionic Exchange Chromatography
    Publication number: 20220145283
    Abstract: The present invention provides new, improved methods for the purification or isolation of a biological molecule of interest, such as plasmid DNA (pDNA) involving an anion exchange (AEX) chromatography step. The method achieves the simple and effective removal of impurities such as RNA, genomic DNA, proteins, cellular fractions, or combinations thereof. The novel methods of the present invention are particularly suitable for large-scale production plants and provide for purified biomolecules (such as pDNA) with excellent quality and good yields, while also allowing for faster processing times and reduced costs.
