    • Provided is a separatome-based recombinant peptide, polypeptide, and protein expression and purification platform based on the juxtaposition of the binding properties of host cell genomic peptides, polypeptides, and proteins with the characteristics and location of the corresponding genes on the host cell chromosome, such as that of E. coli, yeast, Bacillus subtilis or other prokaryotes, insect cells, mammalian cells, etc. This platform quantitatively describes and identifies priority deletions, modifications, or inhibitions of certain gene products to increase chromatographic separation efficiency, defined as an increase in column capacity, column selectivity, or both, with emphasis on the former. Moreover, the platform provides a computerized knowledge tool that, given separatome data and a target recombinant peptide, polypeptide, or protein, intuitively suggests strategies leading to efficient product purification. The separatome-based protein expression and purification platform is an efficient bioseparation system that intertwines host cell expression systems and chromatography.
    • 提供了一种基于分离体的重组肽,多肽和蛋白质表达和纯化平台,其基于宿主细胞基因组肽,多肽和蛋白质的结合性质的并置,其具有相应基因在宿主细胞染色体上的特征和位置, 例如大肠杆菌,酵母,枯草芽孢杆菌或其他原核生物,昆虫细胞,哺乳动物细胞等。该平台定量描述和鉴定某些基因产物的优先缺失,修饰或抑制以提高色谱分离效率,定义为 柱容量增加,色谱柱选择性增加,或两者都增加,重点在于前者。 此外,该平台提供了一种计算机化知识工具,给定分离数据和靶重组肽,多肽或蛋白质,直观地提出了导致有效产品纯化的策略。 基于分离蛋白的蛋白质表达和纯化平台是一种有效的生物分离系统,其交联宿主细胞表达系统和色谱。
