  • Product overview

    Pyrophosphate Assay Kit (Fluorometric) ab112155 provides the most robust spectrophotometric method for the measurement of pyrophosphate.


    The pyrophosphate assay protocol uses a proprietary fluorogenic pyrophosphate sensor that has its fluorescence intensity proportionally dependent upon the concentration of pyrophosphate.


    This pyrophosphate assay protocol is much easier and more robust than enzyme-coupling pyrophosphate methods, which require at least two enzymes for their pyrophosphate detections. Due to its direct measurement of pyrophosphate, this kit is ideal for screening inhibition or activities of enzymes that consume or generate pyrophosphate.


    The pyrophosphate assay is an optimized mix-and-read assay and can be performed in a convenient 96-well or 384-well microtiter-plate format.


    Assay time: 10-30 minutes

  • Notes

    This product measures PPi formation at Ex/Em = 316/456 nm.

    If your instrument has filters for Ex/Em = 370/470 nm, we recommend using Pyrophosphate Assay Kit II (Fluorometric) (ab179836).

    Pyrophosphates (PPi) are produced by a number of biochemical reactions, such as ATP hydrolysis, DNA and RNA polymerizations, cyclic AMP formation by the enzyme adenylate cyclase and the enzymatic activation of fatty acids to form their coenzyme A esters.

    Microplate reader

    Question

    Hi, I have some technical questions about the product 
    Pyrophosphate Assay Kit II (Fluorometric) (ab179836)
     

     

    1) The closest wavelength on my instrument is Ex/Em=355/460 rather than the recommended Ex/Em=370/470 of this product. Do you think I can still use this product to perform my experiments? 

     

    2) Another Pyrophosphate Assay Kit ab112155 uses the wavelength of Ex/Em = 316/456, and it's $80 cheaper than ab179836, do you think I can use either of them or is anyone outperform than the other? 

     

    3) My samples are reaction mixture rather than the described type of tissue or cell extract. Is this product suitable for my experiment?

    Answer

    Thank you for contacting us.

    To answer your questions:

    1) Yes you can use ab179836 with the settings on your instruments

    2) Ab112155 would not work for you, excitation 355 is too high for this kit

    3) Yes, your samples will work with this kit


    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Measuring PPi in mouse serum

    Average Average 3/5 (Ease of Use)

    abreview image
    We wanted to measure PPi in mouse blood. A big problem is the high autofluorescence of serum and plasma, possibly contributed by albumin. Therefore we tested several conditions:
    - untreated serum
    - heat-inactivated serum (45 min 55°C)
    - plasma
    - serum after centrifugation through a 300 kDa cut-off-membrane
    PPi amount was expected in a range between 0.5 - 5 µM [Koba et al. 2005]. Only the last condition (cut-off-membrane) resulted in the expected measurement (approximately 1.62 µM).

    Asked on Jun 26 2015

    Answer

    I can confirm that SDS, Tween-20, and EDTA (> 30 um) will interfere with the assay. Since RIPA buffer has SDS in it, it is not suitable.

    TritonX-100 up to 0.5% does not interefere.

    Asked on May 21 2015

    Answer

    1. What are the maximum and minimum limits of detection?

    The detection limit is ˜0.3 - 1 uM and the Max is 10 uM for ab112155, and 1 mM for ab179836.

    2. Are the assays compatible with citrated plasma (plasma collected with citrate)?

    Citrated plasma will not be a problem, but adjust to pH 7 with Hepes buffer if possible.

    3. Is there any cross-reaction with phosphates other than pyrophosphate? My samples are mouse plasma and urine.

    No.

    4. What are the advantages of the two assays, 21614 vs.21611? Why would I choose one over the other?

    Ab112155 has a slightly lower detection limit (˜0.3 uM), but more ATP interference. Ab179836 has better linearity, and can detect as high as 1 mM PPI.
