Boost your cancer research with our premium Recombinant Human MMP12 protein. Macrophage metalloelastase (MMP12), also known as MME or macrophage elastase, is a matrix metalloproteinase that plays a crucial role in extracellular matrix remodeling, tissue repair, and immune response. With implications in the progression of various cancers, MMP12 is a key target for understanding tumor invasion, angiogenesis, and metastasis.

Our Recombinant Human MMP12 protein has been meticulously produced in E. coli to guarantee optimal quality and performance. The protein sequence represents the full length of the mature protein (106-470 amino acids), ensuring that the native structure and functionality are retained. The N-terminal 6xHis-tag enables efficient purification while maintaining the integrity of the protein's activity. With a purity greater than 90% as determined by SDS-PAGE, our Recombinant Human MMP12 protein is the ideal choice for your research in the field of cancer biology.

Target Background

May be involved in tissue injury and remodeling. Has significant elastolytic activity. Can accept large and small amino acids at the P1' site, but has a preference for leucine. Aromatic or hydrophobic residues are preferred at the P1 site, with small hydrophobic residues (preferably alanine) occupying P3.
