Abstract:
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.

The Extracellular Matrix
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...
