Increased levels of threonyl-tRNA synthetase in a borrelidin-resistant Chinese hamster ovary cell line.
The growth of Chinese hamster ovary cells in medium containing reduced concentrations of threonine is inhibited by borrelidin, a macrolide antibiotic. Borrelidin-resistant clones have been isolated after ethyl methanesulfonate mutagenesis. One clone, 1C-1, has a 3-fold increased level of threonyl-tRNA synthetase [L-threonine:tRNAThr ligase (AMP-forming), EC 6.1.1.3] as determined by both activi...
متن کاملEXPRESSION 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 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...
متن کاملInterphase Death of Chinese Hamster Ovary Cells Exposed to Accelerated Heavy Ions
Introduction: Heavy ions are nucleus of elements of iron, argon, carbon and neon that all carry positive electrical charges. For these particles to be useful in radiotherapy they need to accelerated to high energy by more than thousand mega volts. Also the cosmic environment is considered to be a complicated mixture of highly energetic photons and heavy ions such as iron. Therefore, the health ...
متن کاملP-234: Expression of Human Chorionic Gonadotropin (hCG) Hormone Using Chinese Hamster Ovary Cells
Background: Human chorionic gonadotropin (hCG) is a member of glycoprotein hormones family consist of two different non-covalently heterodimeric chains: alpha and beta subunits with 92 and 145 amino acids respectively. This hormone plays an important role in human reproduction and physiology especially for maintenance of the corpus luteum during the first months of pregnancy Materials and Metho...
