Obtaining high-throughput electrophysiological recordings is an ongoing challenge in ion channel biophysics and drug discovery. One particular area of development is the replacement of glass pipettes with planar devices in order to increase throughput. However, successful patch-clamp recordings depend on a surface coating which ideally should promote and stabilize giga-seal formation. Here, we ...
Chinese hamster ovarian cells (CHO) cells have been extensively utilized for industrial production of biopharmaceutical products, such as monoclonal antibodies, human growth hormones, cytokines, and blood-products. Recent advances in recombinant DNA technology have resulted in the bioengineering of CHO cells that have robust gene amplification systems and can also be adapted to grow in suspensi...
Background Follicle stimulating hormone (FSH)- a hetrodimeric glycoprotein- is secreted by pituitary gland. This hormone stimulates growth and maturation of the follicles in females and sperms in male. Up to now, glycoprotein hormones such as FSH have produced in different cell lines. Among of the mammalian expression systems, the Chinese hamster ovary cells (CHO) have taken into consideration ...
Twenty Serratia marcescens isolates from clinical specimens were examined for their cytotoxic activity on four cell lines (HEp-2, Vero, CHO, J774). Most of the isolates were found to be cytotoxic to CHO (70%), Vero (75%) and HEp-2 cells (90%). CHO cells were the most sensitive to cell-free supernatants, followed by HEp-2 and Vero cells. Two strains produced cytotonic toxins which caused elongat...
Thrombospondin is a 420-kD platelet alpha-granule glycoprotein that binds specifically to heparin. We examined adhesion to thrombospondin of CHO K1 cells and three mutant CHO lines with varying deficiencies in glycosaminoglycan (GAG) synthesis. In an experiment in which the parent line (K1) had 78% adherence to thrombospondin adsorbed to tissue culture plastic, CHO S745 cells, with less than 6%...
Integrin ανβ3 plays a major role in various signaling pathways, cell apoptosis, and tumor angiogenesis. To examine the functions and roles of ανβ3 integrin, a stable CHO-677 cell line expressing the murine ανβ3 heterodimer (designated as "CHO-677-mανβ3" cells) was established using a highly efficient lentiviral-mediated gene transfer technique. Integrin subunits αν and β3 were detected at the g...
Chinese hamster ovary (CHO) cells are a source of multi-ton quantities of protein pharmaceuticals. They are, however, immortalized cells, characterized by a high degree of genetic and phenotypic diversity. As is known for any biological system, this diversity is enhanced by selective forces when laboratories (no sharing of gene pools) grow cells under (diverse) conditions that are practical and...
Background: Cultivated mammalian cells, because of their capacity for proper protein folding, assembly and post–translational modification, have become the dominant system for production of recombinant proteins in clinical application. Therefore, the quality and efficacy of protein can be superior when expressed in mammalian cells compared to other hosts such as bacteria. Gene reporte...
