Product Description

Product Description

HB-EGF (Heparin-binding EGF-like growth factor) is a growth factor which belongs to EGF family and it is a ligand of a receptor tyrosine kinase of ErbB family such as EGF receptor and ErbB4. HB-EGF exists as 3 types of form and the forms are transmembrane (proHB-EGF), soluble HB-EGF (sHB-EGF) which has been cleaved by protease at surface of cells and C terminal fragment (HB-EGF-CTF) which is remained at cell membrane after it has been cleaved. These forms of HB-EGF have different physiological activities. HB-EGF expresses in various cells such as epidermal cells, cardiac myocyte, vascular endothelial cells, smooth myocyte and macrophage. HB-EGF which is secreted in blood involves with cells proliferation, differentiation and inflammatory reaction. It has important roles not only maintaining of physiological functions especially in morphogenesis of the development and in pathogenesis. In recent years, it attracts attentions as a drug target of molecularly-targeted drugs because it has been reported that over-expression of HB-EGF is essential for cancer invasion and metastasis. Human HB-EGF form which contains pro-region can be quantitatively measured by this ELISA kit.

FAQ

FAQ

  • Question
    Q.What is the standard derived from?
  • Answer
    A.It is derived from animal cells.
  • 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.
