Product Description

α-klotho (Alpha Klotho) was identified as an extremely down-regulated gene in the genetically-modified mouse of which phenotype is very similar to various symptoms of human aging. Then, the sequences of Alpha Klotho genes have been identified in various species including humans based on the one of mouse. Alpha Klotho protein is a 130 kDa, one-transmembrane protein and its expression is confirmed in the kidneys and the parathyroid glands. In recent years, it has become clear that Alpha Klotho is an important molecule within a living organism regulating the metabolism of mineral such as calcium and phosphorus. Therefore, it is considered that, in Alpha Klotho mouse, early aging-like symptoms are induced by impaired mineral homeostasis caused by decreased expression of Alpha Klotho. Meanwhile, it is reported that the long N-terminal extracellular domain which comprises the major portion of sequence of Alpha Klotho protein is released free into blood by shedding. However, there are many unclear points about functions and changes in concentration of free (soluble) Alpha Klotho protein, so it has been required to develop the measurement system of Alpha Klotho. This ELISA kit can measure mouse soluble Alpha Klotho protein in mouse urine.

  • Question
    Q.What is recommended dilution ratio?
  • Answer
    A.8 fold dilution is acceptable for the measurement, however, we recommend to dilute mouse urine sample more than 16 fold to avoid the data becomes range over.
  • Question
    Q.Can rat sample be used for this kit?
  • Answer
    A.No, it cannot.
  • Question
    Q.Is stability data available?
  • Answer
    A.It is available on the following relevant product page as images.
  • 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.
