A method for the production and purification of biologically active recombinant human interferon-α-2b (rhIFN-α-2b) that was synthesized as a result of expression in Nicotiana benthamiana plants has been developed. A genetic construct containing the modified gene of hIFN-α-2b was cloned in either of two vectors, first based on tobacco mosaic virus driven by the actin promoter of Arabidopsis thaliana (pA-IFN-A), and second, on cauliflower mosaic virus driven by the 35S promoter (pA-IFN-S). The expression vectors were delivered into the plant cells by agroinjection. The maximal synthesis rate was detected 5 days after the injection and was up to 200 mg and 20 mg per kg of fresh leaves for pA-IFN-A and pA-IFN-S, respectively. The recombinant plant-made hIFN-α-2b had as high antiviral and antitumor activity as a commercial drug.

Key words:  His-tag,  production in plants,  rhIFN-α-2b.
