Product Description

Periostin is approx. 90kDa, an extracellular matrix protein that expresses on an outer membrane of bone and a periodontal membrane. It has a function as a ligand ofαVβ3 andαVβ5 and it involves cell migrant and cell adhesion. In addition, it has been known that it binds extracellular matrix protein such as collagen, fibronectin and tenascin C. In recent year, it has been reported that periostin is elevated in pancreatic cancer. Some research and development of drugs and in vitro diagnostic maker using neutralizing antibody have been conducted as it has also been suggested that periostin may involves with allergy such as heart failure and bronchitis.

  • Question
    Q.What is different between reagent blank and test sample blank?
  • Answer
    A.Reagent blank means a well is only added EIA buffer and the purpose is confirming whether the measuring value is influenced by lack of washing process. Test sample blank means a well is added EIA buffer and HRP antibody and the purpose is to calculate the background.
  • Question
    Q.How many samples can be measured by this kit?
  • Answer
    A.The pre-coated plate contained in our ELISA kit is 96 wells plate. We recommend to use 16 wells (2 slits) for standard and 80 wells (10 slits) for 40 samples in duplicate.
