Product Description

Product Description

Osteopontin (OPN) is a secreted glycoprotein that was originally isolated from bone. At present, it is known as a highly acidic calcium-binding glycosylated phosphoprotein secreted by many cell types, including osteoblasts, kidney tubule cells, macrophages, activated T cells, and vascular smooth muscle cells. Its molecular weights have been reported in the range of 66 kDa to 44 kDa depending on glycosylation and phosphorylation. One important feature of OPN is that it contains an Arg-Gly-Asp (RGD) amino acid sequence. This motif is present in fibronectin, vitronectin and a variety of other extra cellular proteins that bind members of the integrin family of cell surface receptors such as αvβ3. Another important of OPN is is the presence of various molecular forms in vivo due to differential RNA splicing, glycosylation, phosphorylation, sulfation, and susceptibility to proteases. Both OPN and thrombin are likely to be localized together at the site of injury, in- flammation, and angiogenesis and in tumor tissues. Osteopontin is susceptible to proteolytic fragmentation, and this process may have physiologic importance. A report demonstrated that thrombin treatment enhanced OPN cell adhesive activity, suggesting that cleavage of OPN by thrombin exposes a cryptic adhesive sequence. More recently, it was shown that an aminoterminal OPN fragment contains a cryptic binding site that can be recognized by α9β1 integrin. Furthermore, OPN contains multiple cell binding sites and interacts with various receptors; these interactions may have distinct functional. The kit can specifically assay for Rat Osteopontin (OPN) , and can not assay thrombin-cleaved Rat OPN fragments.

FAQ

FAQ

  • Question
    Q.Can this kit be used for supernatant samples that contain FBS?
  • Answer
    A.Yes it can.
  • Question
    Q.Can this kit be used for cleaved type of Osteopontin?
  • Answer
    A.No it cannot.
  • Question
    Q.Can this kit be used for serum samples?
  • Answer
    A.No, it cannot.
  • Question
    Q.Can this kit be used for heparin-plasma samples?
  • Answer
    A.We do not recommend using heparin plasma with the kit. The use of this plasma can affect the measurement results.
  • Question
    Q.Can this kit be used for bovine samples?
  • Answer
    A.No, it cannot.
  • 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.
