  • 产品概述

    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.

    Pyrophosphate Assay Kit (Fluorometric) provides the most robust spectrophotometric method for the measurement of pyrophosphate. It uses a proprietary fluorogenic pyrophosphate sensor that has its fluorescence intensity proportionally dependent upon the concentration of pyrophosphate. Abcam's assay 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 assay is an optimized mix-and-read assay and can be performed in a convenient 96-well or 384-well microtiter-plate format. The kit provides all the essential components for assaying pyrophosphate.

  • 说明

    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).

    • Pyrophospfate measured in cell lysates showing quantity (nmol) per 106cells

    • Pyrophosphate measured in tissue lysates showing quantity (nmol) per microgram protein

    • Pyrophosphate measured in biofluids showing concentration (micromolar). Obtained values were recalculated from 1:1000 sample dilutions.

    • Pyrophosphate, ATP and phosphate dose responses were measured with ab112155 in a solid black 96-well plate using a fluorescence microplate reader. As low as 1 µM (100 picomoles/well) pyrophosphate can be detected with 10 minutes incubation.

    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 sample...

    Thank you for your kind response. It is a pleasure to help in any way I can. Please let me know if you have any questions or there are other ways that Abcam may help you meet your research goals.

    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.


    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)? Read More

    The components of this buffer should not interfere with this assay.

    Thank you for contacting us. I did contact the lab regarding whether ATP or dATP in samples will compromise the sensitivity of the assay and they did not think it would have much effect. Please let me know if you have any further questions.

    37C should be no problem. We did not test with a higher temperature, however, 50C might be OK in theory.

    It is a proprietary dye so unfortunately we can't disclose the structure.

    Thank you for your enquiry.

    I can confirm that the ab112155 Pyrophosphate Assay Kit (Fluorometric) uses a PPi chelator. The fluorescence of the chelator is increased upon forming a complex with PPi. The fluorescence increase is proportional ...
