Product Description

Oligomerization of Amyloidβ (Amyloid Beta) 42 is considered as an early event in Alzheimer ’s disease (AD). Irie et al. have proposed their hypothesis from the study of systematic proline scanning and solid-state NMR that Amyloid Beta conformer with a turn structure at positions 22 and 23 in aggregation of Amyloid Beta 42 is much high toxicity and it is also easily formed to become an oligomer.1) It has been considered that the toxic Amyloid Beta conformer is stable and easily formed to become a neurotoxic oligomer. The antibody (clone: 24B3) specifically detects a toxic Amyloid Beta conformer was established for development of the ELISA assay kit.2) This kit can measure selectively putative Amyloid Beta Oligomer in CSF.

  • 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.
  • Question
    Q.Do you have any protocol for preparation of mice and/or rat brain
    tissue extracts?
    (ELISA common FAQ * Specified FAQ for ELISA that is applicable for brain tissue extract.)
  • 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.

    Presenilin-2 mutation causes early amyloid accumulation and memory impairment in a transgenic mouse model of Alzheimer's disease. Toda T et al. J Biomed Biotechnol. 2011;2011:617974.
