Principle of the Assay: COL-2 ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-COL-2 antibody and an COL-2-HRP conjugate. The assay sample and buffer are incubated together with COL-2-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the COL-2 concentration since COL-2 from samples and COL-2-HRP conjugate compete for the anti-COL-2 antibody binding site. Since the number of sites is limited, as more sites are occupied by COL-2 from the sample, fewer sites are left to bind COL-2-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The COL-2 concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
enzyme that degrades collagen type I [RGD, Feb 2006]
Uniprot Description
Plays a role in the degradation of extracellular matrix proteins including fibrillar collagen, fibronectin, TNC and ACAN. Cleaves triple helical collagens, including type I, type II and type III collagen, but has the highest activity with soluble type II collagen. Can also degrade collagen type IV, type XIV and type X. May also function by activating or degrading key regulatory proteins, such as TGFB1 and CTGF. Plays a role in wound healing, tissue remodeling, cartilage degradation, bone development, bone mineralization and ossification. Required for normal embryonic bone development and ossification. Plays a role in the healing of bone fractures via endochondral ossification. Plays a role in wound healing, probably by a mechanism that involves proteolytic activation of TGFB1 and degradation of CTGF. Plays a role in keratinocyte migration during wound healing. May play a role in cell migration and in tumor cell invasion ().

Product Notes
The Bovine Collagenase II mmp13 (Catalog #AAA746413) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA746413 ELISA Kit recognizes Bovine Collagenase II. It is sometimes possible for the material contained within the vial of "Collagenase, Type II, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
