一般描述
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
应用
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.

外形
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.
制备说明
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.
分析说明
MMP-9 monomer appears as a major band at 92 kDa in non-reducing SDS-PAGE
其他说明
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

Abdominal aortic aneurysms (AAA) are characterized by disruption and degradation of the elastic media, yet the elastolytic proteinases involved and their cellular sources are undefined. We examined if 92-kD gelatinase, an elastolytic matrix metalloproteinase, participates in the pathobiology of AAA.
Interaction of 92-kDa type IV collagenase with the tissue inhibitor of metalloproteinases prevents dimerization, complex formation with interstitial collagenase, and activation of the proenzyme with stromelysin.
