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. 

FAQ

  • Question
    Q.Is composition of EIA buffer of each ELISA kit all same? Can it be mixed to use?
    ELISA common FAQ
  • Answer
    A.No it isn't. As constitute of each EIA buffer is different, it cannot be mixed with other lots or EIA buffers contained in other kind of ELISA kits.
  • Question
    Q.What is the composition of concentrated wash buffer?
    ELISA common FAQ
  • Answer
    A.It contains ordinary Tween and phosphate buffer (0.05% Tween-20 in PB).
  • Question
    Q.What is the feature of the plate?
    ELISA common FAQ
  • Answer
    A.We use plate that is flat bottom and removable strip type plate (8wellx 12 strips).
  • Question
    Q.Can I re-use standard after reconstitution?
    ELISA common FAQ
  • Answer
    A.Not recommended to re-use standard after reconstitution. Please use it at once after the reconstitution.
    Please note that there are some exceptions. One time freeze-thaw the standard is acceptable for use after reconstitution for some ELISAs.
    Please check the details on each product datasheet.
  • Question
    Q.What is different between reagent blank and test sample blank?
    ELISA common FAQ
  • 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?
    ELISA common FAQ
  • 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.
  • Question
    Q.What is LOD (Limit of Detection)?
    ELISA common FAQ
  • Answer
    A.It (LOD) is defined as sensitivity that is calculated using the NCCSL method. Please refer to a datasheet of each product.
  • Question
    Q.What is LOQ (Limit of Quantification)?
    ELISA common FAQ
  • Answer
    A.It (LOQ) is the lowest value of measurement (standard) range. Please refer to a datasheet of each product.
