Product Description

Product Description

FGF19 subfamily composed of FGF19, FGF21 and FGF23 binds the receptors, α/βKlotho and it is characterized as a factor group which has hormonal functions. The novel system consisted of α/βKlotho and FGF19 subfamily regulates integrally metabolism of minerals, lipids, energy and amino acids. This novel regulating system involves important homeostatic mechanism for biological body such asmetabolism of bile acid and cholesterol in the liver (FGF19), energy and glycolipids metabolism (FGF21) and phosphate, calcium and vitamin D metabolism in kidney (FGF23) in fasting state. FGF21 is secreted in the liver and it is reported that it has a lipolytic action in fatty tissues. FGF21 binds a receptor consisted of FGFR and βKlotho. FGF21 reacts in emptiness and it accelerates lipid metabolism in liver, Triacylglycerol (TG) is used as lipid acid and Ketone bodies are produced by the metabolism. As a result, it is used as an energy source. In this process, FGF21 is released and acts as a hormone-like factor. In relation to the concentration of FGF21 in blood, it is measured and reported that the correlation with many diseases like gestational diabetes mellitus, mitochondrial dysfunction in HIV infection, friedreich ataxia, coronary artery disease, carotid atherosclerosis, non-alcoholic fatty liver disease, rheumatoid arthritis, diabetic nephropathy, type2 diabetes, dyslipidemia and, obesity and metabolic syndrome. This kit can assay Human blood FGF21 density.

FAQ

FAQ

  • Question
    Q.Which isoform of FGF21 can detect by this kit?
  • Answer
    A.This assay kit react to both full length FGF 21 (1-181) and FGF21 (7-181). Therefore, this kit can measure total FGF21.
  • 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
    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.What is the definition of Over Night (O/N) reaction?
    ELISA common FAQ
  • Answer
    A.It means that the reaction is required more than 16 hours unless otherwise specifically defined it on a datasheet of each ELISA product.
  • Question
    Q.What is the specification of quality control for ELISA product release?
    ELISA common FAQ
  • Answer
    A.The information of specification is available on individual lot specific CoA. Please contact us with your reference lot number for obtaining of specific CoA.
  • Question
    Q.What is the number (e.g. 432143214321) at the edge of strips of the plate?
    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?
    ELISA common FAQ
  • Answer
    A.Washing it by an auto-washer is highly recommended.
    If it is not available, please refer to the demo video (only 2 mins) using a washing bottle.
  • Question
    Q.The wells turned black during the test with the kit.
    ELISA common FAQ
  • Answer
    A.It is possible that the wells were not washed sufficiently during the washing process after the HRP-labeled antibody reaction.
    Be sure to wash the wells enough times as described in the data sheet with washing buffer of more than 350 µL.
  • Question
    Q.How do you define the acceptance range of quality control of control sets?
    Control Set Common FAQ
  • Answer
    A.In principal, it is defined as ±15%-20% based the standard value described on each datasheet.
  • Question
    Q.What is the shelf life of control set?
