This paper is aimed to present a research on fusion protein of human tumor necrosis factor-alpha (hTNF-alpha), matrix metalloproteinase 1 (MMP1), and foldon sequence using the methord of gene engineering. We transformed the recombinant plasmid, which contains the DNA sequences of hTNF-alpha, MMP1, and foldon sequence, into Rosetta2, and successfully induced the fusion protein to express under given conditions by isopropyl beta-D-1-Thiogalactopyranoside (IPTG). Then we purified the expression product through a glutathione S-transferase (GST) resin and collected the interested protein. This research may lay the groundwork for scientific research and clinical application.
