Product Description

Product Description

The first case of Alzheimer's disease was defined and reported in 1907 by the German scientist, Dr. A. Alzheimer. His studies have shown that this is the main cause of dementia in the elderly. The plaques which appear in the brains of individuals who suffer AD are mostly constituted by the Amyloidβ protein (Aβ). Aβ is a peptide which consists of 40 or 42 (43) amino acids, and reports show that this is cleaved from β- and γ- secretase from the amyloid precursor protein. APP is a trans-membrane protein consisting of 695, 751, or 770 amino acids.　Reports have shown many variants of Aβ exist and are clarified into the culture supernatant from the APP cDNA transfected mouse neuroblastoma cell. Furthermore, in 1995, a dominant and differential deposition of distinct βamyloid peptide species, Aβ(N3pE), in senile plaques was found by Saido et al. This modified molecule, starting at the 3rd amino terminal residue, glutamate, was discovered to convert to pyroglutamate through intramolecular dehydration. This kit measures Aβ(1-42) including variants cleaved N-terminal side by any cause. IBL has many other kinds of Amyloidβ-related products for AD research. They are very specific assay systems for each target and they can be used according to the purpose of study.

FAQ

FAQ

  • Question
    Q.Can this kit be used for the brain extracts from transgenic mice with Alzheimer's disease?
  • Answer
    A.yes, it can.
  • Question
    Q.Can this kit be used for monkey samples?
  • Answer
    A.Because the epitopes of monkeys and human beings are the same, we believe the kit can also be used for monkey samples. However, we do not have any data to back this claim.
  • Question
    Q.Do you have any protocol for preparation of mice and/or rat brain
    tissue extracts?
  • Answer
    A.CHAPS is recommended for extractin of wild type (W.T.) mice or rat brain tissue.
    Please refer to the following link for the brain tissue extraction process using CHAPS.

    Guanidine solution is recommended for extraction of Transgenic (Tg) mice or rat brain tissue.
    Please refer to the following link and the following two scientific articles for brain tissue extraction process using Guanidine.

  • 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 Test sample value is influenced by lack of washing process or other operations. 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

    ELISA common FAQ
  • Answer
    A.According to the plate maker (ThermoFisher), it does not have any specific meaning as it is just the number of molds.
  • Question
    Q.How to wash an ELISA plate?
