Product Description

Product Description

Endothelins (ETs) are isopeptides produced by vascular endothelium having potent vasoconstriction activity. The peptides are encoded by three separate genes and processed to yield 39 residue Big Endothelin (Big ET) molecule, which are further processed to the 21 amino acid sequences termed Endothelin-1 (ET-1), Endothelin-2 (ET-2) and Endothelin-3 (ET-3). All of members of the endothelin family contain two essential disulfide bridges and size conserved amino acid residues at the C-terminus. The ETs are produced by a variety of issues in vivo, including lung, kidney, brain, pituitary and placenta.

FAQ

FAQ

  • Question
    Q.Why extraction and condensation process using Sep-Pack is required for measuring Endothelin-3 (ET-3) blood samples?
    Is the process essential for the assay?
  • Answer
    A.Measuring ET-3 in blood sample is quite difficult due to very low concentration of ET-3 (reference approx. 0.48pg/mL in normal subject blood sample).
    The extraction and condensation process using Sep-Pack is essential for the assay.
    The assay will be failed without the process.
    The ET-3 in blood sample become much lower than the original concentration after the process and it depends on the collection rate.
    Therefore, it is recommended to prepare larger volume 5mL-10mL of blood sample for ET-3 measurement.
    Please refer to "Attention for sample handling" on page 2 of the datasheet for additional information.
  • Question
    Q.Which region are recognized by the antibodies used by this kit?
  • Answer
    A.The capture antibody (Anti-ET 15-21) recognizes the region at C-terminal of ET-3 and the detection antibody specifically recognizes the region at N-terminal of ET-3.
  • 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.
