• Description of Target: Type IV collagenase, 72-kD, is officially designated matrix metalloproteinase-2 (MMP2). It is also known as gelatinase, 72-kD. MMP-2 plays an essential role in angiogenesis and arteriogenesis, two processes critical to restoration of tissue perfusion after ischemia. MMP-2 expression is increased in tissue ischemia, but the responsible mechanisms remain unknown.1 Matrix metalloproteinases (MMPs) catalyze extracellular matrix degradation. Control of their activity is a promising target for therapy of diseases characterized by abnormal connective tissue turnover. MMPs are expressed as latent proenzymes that are activated by proteolytic cleavage that triggers a conformational change in the propeptide (cysteine switch). The structure of proMMP-2 reveals how the propeptide shields the catalytic cleft and that the cysteine switch may operate through cleavage of loops essential for propeptide stability.2 The gene is localized to 16q21 using somatic cell hybrids and in situ hybridization.3 The standard product used in this kit is recombinant human MMP-2, consisting of 631 amino acids with the molecular mass of 71KDa. The detected MMP-2 includes zymogen and active enzyme.
• Reconstitution and Storage: Store at 4C for 6 months, at -20C for 12 months. Avoid multiple freeze-thaw cycles (Shipped with wet ice.)

• Specificity: Natural and recombinant human total MMP-2
• Additional Information: Range: 156pg/ml-10,000pg/ml
• Additional Information: Principle: Aviva’s human MMP-2 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for MMP-2 has been precoated onto 96-well plates. Standards (NSO, A30-C660) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for MMP-2 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human MMP-2 amount of sample captured in plate.
• Immunogen: Expression system for standard: NS0; Immunogen sequence: A30-C660
• Additional Information: Notes: 1. To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot
  experiment using standards and a small number of samples is recommended.
  2. The TMB Color Developing agent is colorless and transparent before using, contact us freely if it is not the case.
  3. Before using the Kit, spin tubes and bring down all components to the bottom of tubes.
  4. Duplicate well assay is recommended for both standard and sample testing.
  5. Don’t let 96-well plate dry, for dry plate will inactivate active components on plate.
  6. Don’t reuse tips and tubes to avoid cross contamination.
  7. To avoid to use the reagents from different batches together.
  8. In order to avoid marginal effect of plate incubation due to temperature difference ( reaction may be stronger in the
  marginal wells), it is suggested that the diluted ABC and TMB solution will be pre-warmed in 37C for 30 min before
  using.
