Expression of soluble recombinant human matrix metalloproteinase 9 and generation of its monoclonal antibody

Abstract

We have successfully produced a recombinant human matrix metalloproteinase 9 (hMMP9) antigen with high yield and purity and used it to generate a hybridoma cell-culture-based monoclonal anti-hMMP9 antibody. We selected the most effective antibody for binding antigens and successfully identified its nucleotide sequence. The entire antigen and antibody developmental procedures described herein can be a practical approach for producing large amounts of monoclonal antibodies against hMMP9 and other antigens of interest. Additionally, the nucleotide sequence information of the anti-hMMP9 monoclonal antibody revealed herein will be useful for the generation of recombinant antibodies or antibody fragments against hMMP9.
