Intraclonal Protein Expression Heterogeneity in Recombinant CHO Cells
Therapeutic glycoproteins have played a major role in the commercial success of biotechnology in the post-genomic era. But isolating recombinant mammalian cell lines for large-scale production remains costly and time-consuming, due to substantial variation and unpredictable stability of expression amongst transfected cells, requiring extensive clone screening to identify suitable high producers...
متن کاملCloning and Expression of Recombinant Human Interleukin-7 in Chinese Hamster Ovary (CHO) Cells
Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...
متن کاملP-152: Expression of Recombinant Human Luteinizing Hormone (hLH) in CHO Cells
Background: Human luteinizing hormone (hLH) stimulates steroid biosynthesis of the ovary, triggers ovulation and prepares androgen production of testicular Leydig cells. LH belongs to the family of glycoprotein hormones that are heterodimers consisting of a common α-subunit and specific β-subunit. hLH is necessary for clinical and infertility treatment. Recombinant DNA technology provides a use...
متن کاملRecombinant VP1 Protein of FMD Virus Type O/IRN/2010 as an Immunogenic Peptide Expression System
Foot and Mouth Disease (FMD) is highly contagious disease among cloven-hoofed animals. FMD virus has structural and non-structural proteins. Vp1 is the most immunogenic structural peptides of FMD virus, applied for major vaccine studies. Objective: Construction of Pet28-VP1 cassette for FMD virus type O/IRN/2010 and expression VP1 peptide as the most immunogenic antigen was the aim of this stud...
متن کاملInfluence of glutamine on transient and stable recombinant protein production in CHO and HEK-293 cells
Background Glutamine is an essential component in culture media for most of the mammalian cell lines. It is often used as an alternative source of energy by cells, along with glucose. Glutamine metabolism induces ammonia accumulation in cell culture. Elevated ammonia concentration above 2 mM has been shown to have negative impact on both cell growth and recombinant protein productivity [1-4]. I...
