Beschreibung

General description

Native MMP-9-Lipocalin-TIMP-1 complex from stimulated human neutrophils. The ternary MMP-9/lipocalin/TIMP-1 complex behaves like the progelatinase B/TIMP-1 complex in acting as an inhibitor of active MMPs. Following activation, the complex acts as a gelatinase with reduced activity.

Note: 1 mU = 1 milliunit.

Physical form

In 200 mM NaCl, 50 mM Tris-HCl, 5 mM CaCl₂, 1 µM ZnCl₂, 0.05% Brij^® 35 Detergent, 0.05% NaN₃, pH 7.0.

Preparation Note

Following initial thaw, aliquot and freeze (-70°C).

Prepared from stimulated neutrophils that have been shown by certified tests to be negative for HBsAg and for antibodies to HIV and HCV.

Other Notes

Kolkenbrock, H., et al. 1996. Biol. Chem. 377, 529.

One unit is defined as the amount of enzyme that will hydrolyze 1.0 µmol 2,4-DNP-Pro-Gln-Gly-Ile-Ala-Gly-Gln-D-Arg-OH per min at 37°C, pH 7.0.
