  • Product overview

    ATP Assay Kit (Colorimetric/Fluorometric) (ab83355) is designed to be a robust, simple method which utilizes the phosphorylation of glycerol to generate a product that is easily quantified by colorimetric (ODmax = 570 nm) or fluorometric (Ex/Em = 535/587 nm) methods.

    This kit can detect as low as 1 µM of ATP in various samples.

     If you require a more sensitive product, we recommend Luminescent ATP Detection Assay Kit (ab113849), which can detect as low as 1 pM of ATP.

  • Notes

    ATP is the primary energy currency of living systems. Virtually all energy requiring processes utilize the chemical energy stored in the phosphate bond of ATP. ATP is formed exclusively in the mitochondria and a variety of genetic diseases can affect ATP formation in the mitochondria.

Customer reviews and Q&As

Unfortunately, we have not tested the interference of desferrioxamine with this kit.

This assay utilizes an oxired probe reaction. ATP is used during enzymatic phosphorylation of glycerol and the byproduct of this reaction eventually oxidizes the probe to form Resorufin which is measured by absorbance or fluorescence. The higher the AT...

Thank you for contacting us at Abcam Scientific Support.

I am happy to assist with your protocol inquiries.

1) The instruction booklet says to homogenize of the sample with ATP assay buffer first and then deproteinize using PCA and ...

Since there are enzymes in the assay which might need metal ions for function, we do not recommend metal chelators like EDTA for blood collection. Heparin is a better choice.

Generally, fresh samples are best, but frozen samples can be used with this kit. We suggest snap-freezing cells or tissue, and deproteinizing lysates before freezing, for best results.

Using a 561 nm excitation rather than the recommended 535 nm would compromise the results. Typically, bandpass filters are +/- 10nm, so you're 561 nm excitation would have a flexibility of 551 - 571 nm. If you do not have the means of exciting at 535 n...

For the colorimetric assay, use a clear plate. For the fluorometric assay a clear or a white plate can be used. Use flat bottom plates.

This kit will detects total ATP.

Yes, you will have to use a homogenizer to ensure proper tissue lysis in the assay buffer. Any type of homogenizer that you prefer can be used, and as shown on the datasheet, we recommend deproteinizing sample isolation preferably with PCA rather than ...
