MMP-12 蛋白, Human

MMP-12 protein is potentially engaged in tissue injury and remodeling, displaying significant elastolytic activity. It shows flexibility at the P1' site, accommodating both large and small amino acids, yet favoring leucine. At the P1 site, it prefers aromatic or hydrophobic residues, with a tendency for small hydrophobic residues like alanine in the P3 position. MMP-12 Protein, Human is the recombinant human-derived MMP-12 protein, expressed by E. coli , with tag free. The total length of MMP-12 Protein, Human is 163 a.a., with molecular weight of ~18 kDa.

MMP-12 蛋白可能参与组织损伤和重塑，并具有显着的弹力分解活性。它表现出在 P1' 位点接受大氨基酸和小氨基酸的能力，尽管它表现出对亮氨酸的偏好。在 P1 位点，它有利于芳香族或疏水性残基，在 P3 位点偏爱小的疏水性残基，如丙氨酸。

Measured by its ability to cleave the fluorogenic peptide substrate, Mca-PLGL-Dpa-AR-NH2 and the specific activity is > 800 pmoles/min/µg.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 10 mM Hepes, 2 mM CaCl₂, 250 mM NaCl, pH 7.0. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
