Product Description

Product Description

Alzheimer’s disease (AD) was first reported by A. Alzheimer, a German neuropathologist in 1907 and is considered as a major factor of senile dementia. It is known that Amyloid β (Aβ; which is a major constituent of senile plaque) is cleaved from Amyloid Precursor Protein (APP; which exists in three main isoforms, APP695, APP751, and APP770) by β-secretase and subsequent γ-secretase. On the one hand, it has been also reported there is βCTF (β-secretase C-terminal fragment), fragments which are cleaved by β-secretase but not by γ-secretase. It is thought that measuring βCTF, in addition to Aβ, soluble APPα and APPβ, also has significance in research of the metabolic pathway of APP. This ELISA can measure human APP βCTF in samples such as cultured cell lysate.

FAQ

FAQ

  • Question
    Q.Can mouse or rat samples be used for this kit?
  • Answer
    A.Wild type mouse or rat samples cannot be used, but APP-transgenic (Tg2576) mouse can be used for the kit.
  • Question
    Q.Is there any recommended buffer solution for cell extraction?
  • Answer
    A.We recommend to use our product #19022 IBLysis.
  • Question
    Q.What is the epitope of the antibodies used in this kit?
  • Answer
    A.The epitope of HRP conjugated labeled antibody (Anti-Human Aβ (N) (82E1) Mouse IgG MoAb Affinity Purify at N-Terminal) used in this kit is DAEFRHDSGYEVHHQK.
    The epitope of the precoated plate antibody (Anti-Human APP-C Rabbit IgG Affinity Purify at C terminal) used in this kit is NGYENPTYKFFEQMQN.
  • 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.
