EXPRESSION OF HUMAN PROTEINASE 3 IN CHINESE HAMSTER OVARY CELLS (CHO-CELLS)
Proteinase 3(PR3) is a human polymorphonuclear leukocyte serine proteinase and is the main target antigen for antineutrophil cytoplasmic antibodies (ANCA) found in Wegener's granulomatosis (WG). We developed a stable expression system for conformationally intact recombinant PR3 (rPR3) in Chinese hamster ovary cells (CHO-cells). The part of PR3 cDNA that encoded the active form of PR3 was s...
متن کاملChromosome identification and its application in Chinese hamster ovary cells
Introduction Chinese hamster ovary (CHO) cells [1] are today a very important host for the commercial-scale production of protein pharmaceuticals. Two sub clones of CHO cells, proline-requiring CHO K1 [2] and the dihydrofolate reductase (DHFR) gene-deficient CHO DG44 [3], are the most widely used for both scientific research and industrial applications [4][5,6]. Previously, we constructed a gen...
متن کاملDaunorubicin-resistant Chinese hamster ovary cells expressing multidrug resistance and a cell-surface P-glycoprotein.
Independent lines of Chinese hamster ovary cells resistant to the antineoplastic drug, daunorubicin, were obtained by clonal isolation in increasing drug concentrations. A single daunorubicin-resistant phenotype typified by reduced cellular drug accumulation was observed. These mutants displayed a complex phenotype of resistance to a variety of unrelated drugs. Such properties are similar to th...
متن کاملCytoplasmic inheritance of oligomycin resistance in Chinese hamster ovary cells
Oligomycin-resistant clones were isolated from Chinese hamster ovary cells by treatment of cells with ethidium bromide, followed by mutagenesis with ethylmethane sulfonate and selection in oligomycin. One clone (Olir 8.1) was chosen for further study. Olir 8.1 cells grow with doubling time similar to that of wild-type cells, whether grown in the presence or absence of drug (doubling time of 13-...
متن کاملIntracellular Localization of FLAG-Peroxisomal Protein in Chinese Hamster Ovary (CHO) Cells
Epitope tagging is a method of expressing proteins whereby an epitope for a specific monoclonal antibody is fused to a target protein using recombinant DNA techniques. The aim of this study was to sub-clone the peroxisomal protein (PEP) cDNA into a mammalian expression vector leading to the formation of a chimeric PEP-cDNA containing the FLAG epitope. The FLAG-PEP recombinant cDNA was construc...
