    • The invention reflects enhanced antibody expression of an antibody of interest by cell lines transformed by random homozygous gene perturbation methods to either increase or decrease the expression pattern of a gene of the cell line other than the antibody of interest. The transformed cell line exhibits specific productivity rates, SPR, for the RHGP transformed cell liens of 1.5 or more, as compared with the antibody expressing cell line parents prior to transformation by RHGP. A knock out or anti-sense construct may be devised to reduce expression of the target gene, a promoter may be inserter to enhance expression of the target gene. The antibodies expressed by the transformed cell lines exhibit the binding properties of their parent cell lines prior to transformation with RHGP, and increase Total Volumetric Production of said antibody by said cells in a given volume.
    • 本发明反映了通过随机纯合基因扰动方法转化的细胞系增强或减少除感兴趣抗体之外的细胞系的基因的表达模式的目标抗体的增强的抗体表达。 与通过RHGP转化之前与抗体表达细胞系亲本相比,转化细胞系表现出1.5GP以上RHGP转化细胞留置量的比生产率SPR。 可以设计敲除或反义构建体以减少靶基因的表达,启动子可以被插入以增强靶基因的表达。 由转化的细胞系表达的抗体在用RHGP转化之前表现出其亲本细胞系的结合特性,并且增加所述细胞在给定体积中的所述抗体的总体积产量。
