General description
When measured with the peptide substrate dinitrophenyl-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg [Masui et al., 1977] the specific activity of MMP-9 monomer
Application
ACTIVATION:
An aliquot of 10 μL MMP-9 monomer is mixed with 20 μL trypsin solution (see below) and activation buffer in a total volume of 100 μL. The mixture is incubated for 20 min at 37°C. Thereafter trypsin is inhibited by addition of 10 μL aprotinin solution.
Trypsin solution: 0.50 mg TPCK-trypsin/mL activation buffer. The solution is stored in aliquots at -20°C.
Activation Buffer: 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 5 mM CaCl2.
Aprotinin solution: 1 mg aprotinin/mL activation buffer. The solution is stored at -20°C.

Unit Definition
Specific Activity: where 1 U is the activity that hydrolyzes 1 mmol peptide (7-methoxycoumarin-4-yl)acetyl-Pro-Leu-Gly-Leu-Dpa-Ala-Arg) within 1 minute under the assay conditions described by Knight ,et al
Physical form
Provided as a liquid in 50 mM Tris-HCl, pH 7.0, 200 mM NaCl, 5 mM CaCl2, ,1 μM ZnCl2, 0.05% Brij-35, 0.05% NaN3.
Storage and Stability
Maintain frozen at -70°C in undiluted aliquots. The enzyme may be stored at -20°C for several without significant loss of activity. Repeated freezing and thawing should be avoided.
Analysis Note
MMP-9 monomer appears as a major band at 92 kDa in non-reducing SDS-PAGE
