Expression of Biologically Active Recombinant B-Domain-Deleted Human Factor VIII in Mammalian Cells

مهار بیان ژن GFP به وسیله تداخل RNA (RNAi) در دودمان سلولی کارسینومای جنینی P19

 Introduction: RNA interference (RNAi) is a phenomenon of gene silencing that uses double-stranded RNA (dsRNA), specifically inhibits gene expression by degrading mRNA efficiently. The mediators of degradation are 21- to 23-nt small interfering RNAs (siRNA). The use of siRNAs as inhibitors of gene expression has been shown to be an effective way of studying gene function in mammalian cells.  Ai...

The Effects of Novel Mutations in A1 Domain of Human Coagulation Factor VIII on Its Secretion Level in Cultured Mammalian Cells

Inefficient secretion of the human coagulation factor (hFVIII) in mammalian expression systems is one ofthe main causes of the hFVIII low expression level, attributed to its interaction with a chaperone known asBiP/GRP78. In order to improve secretion efficiency of the hFVIII, based on the higher secretion level of theporcine FVIII and analysis of the hFVIII A110 region, that ...

Construction of a Mammalian IRES-based Expression Vector to Amplify a Bispecific Antibody; Blinatumomab

Blinatumomab, the bispecific T cell engager, has been demonstrated as the most successful BsAb to date. Throughout the past decade, vector design has great importance for the expression of monoclonal antibody in Chinese hamster ovary (CHO) cells. It has been indicated that expression plasmids based on the elongation factor-1 alpha (EF-1 alpha) gene and DHFR selection marker can be highly effect...

A Comparative Investigation of the Bispecific Antibody: Expression in Expi293F Cells and E.Coli

Aims: Bispecific antibodies are capable of targeting two cell surface markers simultaneously. Blinatumomab an anti-CD3/CD19 Bispecific T cell engager antibody (BiTE) is approved for clinical application by FDA. This BiTE effectively targets malignant cells in ALL (Acute Lymphoblastic Leukemia) patients. For production of large quantities of such antibodies in industrial settings choice of host ...
