Description of Target:
Osteoprotegerin (OPG) is identical to osteoclastogenesis inhibitory factor (OCIF), a soluble member of the tumor-necrosis factor receptor family that inhibits osteoclastogenesis.1 OPG is considered to play an important role in the regulation of bone resorption by modifying osteoclast differentiation.2 Osteoprotegerin is an independent risk factor for the progression of atherosclerosis and onset of cardiovascular disease.3 It can act as a soluble factor in the regulation of bone mass and imply a utility for OPG in the treatment of osteoporosis associated with increased osteoclast activity.4 OPG system may play a critical role in the development of osteolytic bone disease in multiple myeloma and that targeting this system may have therapeutic potential.5 OPG also plays a role in the vascular system.6 The standard product used in this kit is recombinant OPG, a 55KDa glycoprotein.

Kit Principle:
Aviva Systems Biology OPG ELISA Kit (Human) (OKBB00235) is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody specific for OPG has been pre-coated onto 96-wellplate (12 x 8 Well Strips). Standards (NSO, E22-L401) and test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for OPG is added, incubated and followed by washing. Avidin-Biotin-Peroxidase Complex is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is visualized through the addition of TMB substrate which is catalyzed by HRP to produce a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample Human OPG captured in well.

Additional Information:
Range: 93.8pg/ml-6000pg/ml
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
