Invitrogen™ MMP8 Human ELISA Kit

Beschreibung

The Human Matrix MetalloProteinase 8 (Hu MMP8) ELISA quantitates Hu MMP8 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu MMP8. Principle of the method The Human MMP8 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Matrix Metalloproteinase 8 (MMP8) is also known as neutrophil collagenase and collagenase 2. MMP8 degrades fibrillar collagens types I, II, III, aggrecan, serpins and alpha 2 macroglobulin. All collagenases cleave fibrillar collagens at one specific site resulting in generation of N-terminal three-quarter and C-terminal one-quarter fragments, which then denature to gelatin at body temperature. The substrate specificity of collagenases is variable: MMP1 degrades type III collagen more efficiently than type I or type II collagen, whereas MMP8 is more potent in degrading type I collagen than type III or type II collagen. MMP13, in turn degrades type II collagen 6-fold more efficiently than type I and type II collagens and displays almost 50-fold stronger gelatinolytic activity than MMP1 and MMP8. MMP8 is very similar to MMP1, sharing 57 % amino acid identity. Most cell types do not produce MMP8. Until recently, it was thought that MMP8 was produced exclusively by neutrophils, but it has also been detected in other cell types including arthritic chondrocytes and gingival fibroblasts. The human MMP8 gene has the chromosomal location of 11q22.2-22.3.
