Random homozygous gene perturbation to enhance antibody production

Abstract

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.
