  • 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.

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

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.

There are 2 ways you can efficiently lyse your cells for this assay kit. You can either homogenize the 1 x 10^6 cells with 100 ul of the assay buffer using 30-50 passes on ice, check for the homogenization and then deproteinate your samples with the de...

Yes, protease inhibitors can be added during step 1 of the sample preparation step.

The calculations are as follows;

1umol is not micro mole means, it is not molarity it is absolute weight.

1micromol is dilutes in 100ul of water which will give you 1micromol/100ul or 1/100 micromol per ul

Now 10ul of this is...

We are actually working on the preservation of rat pancreas from ischemia-reperfusion injury that occurs during the retrieval of the organ before a transplantation to a recipient. We are looking for strong ischemia markers and we know from literature that ATP level in pancreatic islet before is a good marker to predict transplantation outcomes (Jae Hyeon K et al., 2009. Transplantation).
We extracted ATP from fresh pancreas that have undergo different time of cold ischemia : 0, 2, 4, 6, 8 and 10h. We also extracted ATP in situ. ATP were extracted in Perchloric acid (PCA-2M) and grind using a Polytron. PCA were removed using potassium hydroxide (KOH – 2M) and pH was adjust around 7-8. Samples were conserved at -80°C before utilization.

mean ATP (pmol/well/mg of tissue) SEM
0H ischemia 424,6105618 90,37421351
2H ischemia 41,0225542 7,565889256
4H ischemia 42,510 5,383
6H ischemia 33,643 2,403
8H ischemia 26,986 2,403
10H ischemia 22,424 1,784
12h ischemia 18,24979888 4,449727198

We obtained concording results with literature : a decrease of ATP level in pancreas with time of cold ischemia. This assay is working on pancreatic rat tissue.

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...

Directly homogenizing in PCA makes sure that all proteins are precipitated and enzymes are deactivated right away. This is a good option for muscles since they are highly metabolically active tissues. This will also be helpful for you since this would ...
