Product Summary

The Quantikine Mouse Periostin/OSF-2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure Periostin in cell culture supernates, serum, and plasma. It contains Sf 21-expressed recombinant mouse Periostin and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse Periostin. Results obtained using natural mouse Periostin showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse Periostin.

Recovery

The recovery of mouse Periostin spiked to three levels throughout the range of the assay was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Samples (n=6) 95 81-117

Linearity

To assess the linearity of the assay, samples containing high concentrations of mouse Periostin in each matrix were diluted with Calibrator Diluent and assayed.

Background: Periostin/OSF-2

Periostin, also known as OSF-2, is a secreted matricellular protein with functions in extracellular matrix formation, cell migration, and inflammation. It is secreted as a 90 kDa monomer that can aggregate into >170 kDa higher-order multimers. Periostin is expressed by mesenchymal cells such as vascular smooth muscle cells, fibroblasts, osteoblasts, and odontoblasts in developing teeth. It is upregulated in many carcinomas. Periostin binds to multiple Integrins and enhances cell adhesion and cell migration. It enhances Fibronectin and Collagen I production and promotes collagen fibrillogenesis. It also induces epithelial-mesenchymal transition, tumor growth, invasion, and metastasis. Periostin induces the expression of VEGF R2 on endothelial cells and VEGF-C in tumor cells, and it can induce tumor lymphangiogenesis. Periostin plays an important role in heart valve development and tissue healing after myocardial infarction. In asthma, it is upregulated in bronchial epithelium and plays both destructive and protective roles by inducing eosinophil infiltration and inhibiting goblet cell metaplasia and mucus production.

Assay Procedure

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

  3. 50 µL Assay Diluent
  4.   Add 50 µL of Assay Diluent to each well.

  5. 50 µL Standard, Control, or Sample
  6.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
  7.   Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.

  8. 100 µL Conjugate
  9.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
  10.   Aspirate and wash 5 times.

  11. 100 µL Substrate Solution
  12.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

  13. 100 µL Stop Solution
  14.   Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
