Inducible Expression of Human Gamma Interferon
Background:The premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. Furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. So, it is necessary to tightly control IFN-γ pr...
متن کاملReview on Interferon beta: from cells to clinical usage
Introduction: Interferon (IFN) was first introduced by Isaacs and Linddeman in 1957. It referred to a factor that could cause inhibition in the growth of the live influenza virus. Interferons are intracellular proteins that are involved in many cellular processes such as growth, proliferation, differentiation, metabolism of the extracellular matrix, apoptosis, and regulating immune responses. T...
متن کاملCharacterization of human beta-interferon-binding sites on human cells.
Radioiodinated recombinant human beta-interferon (rHuIFN beta Ser), with almost full (greater than 90%) biological activity, was used to study the binding of human beta-interferon to Daudi cells. Specific binding was not observed with less biologically active (less than or equal to 10%) radioiodinated interferon. The bound radioiodinated interferon was shown to compete with human beta-interfero...
متن کاملOverexpression of Recombinant Human Beta Interferon (rhINF-β) in Periplasmic Space of Escherichia coli
Human Interferon β (INF-β) is a member of cytokines family which different studies have shown its immunomodulatory and antiviral activities. In this study an expression vector was designed and constructed for expression of human INF-β-1b either in shake flasks and bench top bioreactor. The designed vector was constructed based upon pET-25b(+) with T7 promoter. Recombinant human beta interferon ...
متن کاملRadioimmunoassay for human beta interferon.
Pure human beta interferon (Hu IFN-beta) (formerly human fibroblast interferon) was used to raise antibodies in rabbits. Anti-IFN-beta immunoglobulins from rabbit serum were purified by IFN-beta affinity chromatography and were used in the development of a sandwich-type radioimmunoassay for Hu IFN-beta. This radioimmunoassay consisted of (i) incubating Hu IFN-beta with anti-IFN-beta immunoglobu...
