Description

Description
MW = 17.6 kDa. Recombinant matrix metalloproteinase-12 (MMP-12, metalloelastase, macrophage elastase) cloned from human cDNA, expressed in E. coli. The enzyme consists of the catalytic domain of human MMP-12 (residues 106-263, UniProtKB accession P39900).The enzyme has been inactivated by mutagenesis (E219A). This product is derived from MMP-12 Catalytic domain and contain also the mutation F171D to increase its stability. No residual enzyme activity has been detected using the method described in the specific activity section of this data sheet.
