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.

Purity
> 95% by SDS-PAGE. The protein is observed, in denaturing conditions, as a single band migrating at a molecular weight between 14.4 and 18.4 kDa.
 
Supplied as
0.2 mg/mL solution in Tris 20 mM pH 7.2, CaCl2 10 mM, ZnCl2 0.1 mM, NaCl 0.3 M, acetohydroxamic acid (AHA) 0.2 M. The concentration is calculated by the analysis of the absorbance at 280 nm, (ε280 = 26930 M-1cm-1 calculated).
 
Specific activity
Not detected. Activity described as U=100 pmol/min at 25°C using a colorimetric ***** with thiopeptide Ac-Pro-Leu-Gly-[2-mercapto-4-methyl-pentanoyl]-Leu-Gly-OC2H5 (Biomol) as substrate.

Storage
-80°C. After initial defrost, aliquot the product into individual tubes and refreeze at -80°C.
Avoid repeated freeze/thaw cycles.
