Descrição

Descrição geral

Most MMPs (matrix metalloproteinases) are secreted as inactive pro-proteins which are activated when cleaved by extracellular proteinases. MMP-9, also known as 92kDa type IV collagenase, 92kDa gelatinase/gelatinase B (GELB), CLG4B, is secreted from neutrophils, macrophages, and a number of transformed cells, and is the most complex family member in terms of domain structure and regulation of its activity. Structurally, MMP-9 maybe be divided into five distinct domains: a pro-domain which is cleaved upon activation, a gelatin binding domain consisting of three contiguous fibronectin type II units, a catalytic domain containing the zinc binding site, a proline rich linker region, and a carboxyl terminal hemopexin like domain.

Aplicação

MMP-9 human has been used as a standard in gelatin zymography.

Ações bioquímicas/fisiológicas

Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Studies in rhesus monkeys suggest that MMP-9 is involved in IL-8 (interleukin-8)-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling. Thrombospondins, intervertebral disc proteins, regulate the effective levels of MMP-2 and -9, which are key effectors of ECM (extracellular matrrix) remodeling. This enzyme degrades various substrates including gelatin, collagen types IV and V, and elastin. MMP-9 is involved in a variety of autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and multiple sclerosis, and be regarded as a potential therapeutic target. It is also associated with lumbar-disc herniation and metaphyseal anadysplasia.

forma física

Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Generally 5-8% Mannitol or trehalose is added as a protectant before lyophilization.

Reconstituição

Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, it is recommended to store at -20°C.
