P-132: The Effect of Different Fetal Bovine Serum Levels on Recombinant Chinese Hamster Ovary Cells, Expressing HumanFollicle Stimulating Hormone
Background: Follicle stimulating hormone (FSH) is one of the most common and effective gonadotropin hormones used in infertility treatment. Production of FSH as a drug is affordable as long as it is done with minimal cost. FBS is the most expensive component in medium culture furthermore; it’s being controversial to cause unnecessary suffering for the unborn calf for collection their serum. In ...
متن کاملEffects of heat treatment and concentration of fish serum on cell growth in adhesion culture of Chinese hamster ovary cells.
The effects of heat treatment and concentration of fish serum (FS) on cell growth and human granulocyte-macrophage colony-stimulating factor (hGM-CSF) production in an adhesion culture of recombinant Chinese hamster ovary (CHO) cells, DR1000L4N, were investigated. The addition of heat treated FS instead of non-heat-treated FS improved cell growth in terms of cell density, which reached 60% that...
متن کاملP-76: Stepwise Reduction of Fetal Bovine Serum Levels in Chinese Hamster OvaryCells -Expressing Human Chorionic Gonadotrophin- Culture
Background: The demand for producing recombinant therapeutic proteins by mammalian cell lines, such as Chinese hamster ovary (CHO) cells, continues to grow. Significant achievements in process optimization including development of cell culture strategies for largescale and cost-effective production have been made. Fetal bovine serum (FBS) is an often essential growth supplement and yet most cos...
متن کاملChinese hamster ovary cell culture
The effect of 26-hydroxycholesteroI and other intermediates in bile acid synthesis on HMG-CoA reductase activity was studied in Chinese hamster ovary (CHO) cell culture. Incubation of CHO cells for 5 hr in 0.25 PM 26-hydroxycholesterol caused a 40% inhibition of HMG-CoA reductase activity. All other intermediates tested including 3B-hydroxy-5cholenoic acid and cholest-5-ene-3B,7a,26-triol, oxid...
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...
