A Simplified Process for Purification and Refolding of Recombinant Human Interferon-α2b
Background: Interferon α-2b is a vital biotherapeutic produced through the recombinant DNA technology in E. coli. The recombinant IFN-α2b normally appears as intercellular IBs, which requires intensive refolding and purification steps. Method: Purification of IFN-α2b from solubilized IB was performed using two-phase extraction. To optimize refolding conditions, the effects of pH and different a...
متن کاملExpression and Purification of Human Interferon Gamma Using a Plant Viral Vector
A plant viral vector engineered from an in vivo infectious clone of zucchini yellow mosaic virus(ZYMV) was used to express the human interferon-gamma (INF-γ) in planta. The INF-γ gene was in frame inserted between the P1 and HC-Pro ORFs of the ZYMV vector. The infectious activity of the vector was approved by rubbing the plasmid on Chenopodium quino a and observing local lesions. Individual les...
متن کاملUse of an anti-human leukocyte interferon monoclonal antibody for the purification and radioimmunoassay of human alpha interferon.
Mouse monoclonal antibody directed against human leukocyte alpha interferon (IFN-alpha) was coupled to Sepharose and used as an immunoadsorbent to purify human IFN-alpha. Leukocyte and lymphoblastoid (Namalva) IFNs were retained by the immunoadsorbent with a specificity of 80 to 100% and 40 to 60%, respectively. Human IFN-beta or -gamma and mouse IFN were not retained. The purified IFN-alpha re...
متن کاملPharmacokinetic properties of human fibroblast and leukocyte interferon in rabbits.
When rabbits were given intramuscular injections of the same quantities of human leukocyte or fibroblast interferons, the former produced moderately higher levels of circulating interferon. Fibroblast interferon was not cleared faster from circulation, nor was direct inactivation by rabbit blood responsible for this difference.
متن کاملThe absence of introns within a human fibroblast interferon gene.
Experiments in which immobilised restriction fragments of genomic DNA were hybridised with a cloned human fibroblast interferon cDNA indicate that the homologous chromosomal genes exist in only one basic arrangement. This is in marked contrast to recent studies by Nagata et al. (1) showing that there are at least eight gene arrangements for human leukocyte interferon. Having isolated a chromoso...
