Product Description

Product Description

Erc has been identified as a gene showing stronger expression in cancer-affected renal tissue than in normal renal tissue in Eker rats (a rat model of renal cancer). The human homologue of the protein encoded by this gene is called MPF (megakaryocyte potentiating factor) or mesothelin. This protein is detected especially prominently in mesothelial cells, and its involvement has been suggested in the development of mesothelioma, making it a promising tumor marker. In humans, involvement of this protein has also been suggested in the development of pancreatic, ovarian and pulmonary cancers, etc. The protein is expressed as a GPI anchor-type membranous protein (about 71 kDa in molecular weight), which is digested by a furin-like protease to yield fragments about 31 kDa and 40 kDa in size. We have established a system for the assay of this protein, referring to the 31 kDa fragment as N-ERC/Mesothelin. This ELISA kit can measure N-ERC/Mesothelin in human plasma samples.

FAQ

FAQ

  • Question
    Q.Can serum sample be used for this kit?
  • Answer
    A.Not recommended to use serum samples. Please refer to the following article for comparison data between serum and plasma. https://www.ncbi.nlm.nih.gov/pubmed/?term=25045139
  • 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.
