Range 156pg/ml-10,000pg/ml
Sensitivity < 20pg/ml
Specificity: no detectable cross-reactivity with any other cytokine.
Application: for quantitive detection of human MMP-1 in sera, plasma, body fluids, tissue lysates or cell culture supernates.
Expiration: four months at 4°C and eight months at -20°C.
Background
Matrix metalloproteinase-1 (MMP-1) is also known as collagenase. Matrix metalloproteinases (MMPs) are zinc-dependent proteases that degrade extrMMP-1llular matrix proteins. The MMPs comprise a family of at least 20 proteolytic enzymes that play an essential role in tissue remodeling. Matrix metalloproteinase-1 (MMP-1) plays an important role in the degradation of collagen in inflammatory diseases.1 MMP1 (interstitial collagenase), MMP9 (gelatinase B) and MMP12 (macrophage elastase) are thought to be important in the development of emphysema.2 Smoking-induced MMP-1 might be important in the skin-ageing effects of tobacco smoking.3 The standard product used in this kit is human MMP-1 with the molecular mass of 51-53KDa. The detected MMP-1 includes zymogen and active enzyme.
Principle
The ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. The target specific antibodies are precoated onto 96-well plates. The target from the sample is bound to the microwell. The biotinylated target specific detection antibodies are added to the microwells and followed by washing with the PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with the PBS or TBS buffer. TMB, the HRP (horseradish peroxidase) substrate, is used to visualize color change resulting from the HRP enzymatic reaction. TMB is catalyzed by HRP to produce the blue color. The color changes into yellow after the acidic stop solution is added. The density of the yellow color is proportional to the target amount from the sample captured in the microwells.
