Development of MMP13-expressing plasmid. (a) The MMP13 expression vector, containing CAG promoter-MMP13-IRES-tdTomato-polyA cassette, was generated through a multistep and ligation-based cloning (pBGI-MMP13). (b) The expression efficiency of MMP13 from the pBGI-MMP13 was confirmed in vitro by western blotting. Control, standard recombinant MMP13 protein.
