  • Product overview

    ATP Assay Kit (Colorimetric/Fluorometric) (ab83355) use a robust, simple method; the ATP assay protocol relies on 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.

    ATP assay protocol summary:
    - add samples (deproteinized) and standards to wells
    - add reaction mix and incubate for 30 min at room temp
    - analyze with microplate reader

    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.

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.

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 deproteinization kit. Alternatively, you can just lyse your cells in the PCA using the protocol mentioned for the deproteinization kit, neutralize the lysate and use it in the wells. In this case you will have to use the assay buffer for diluting the samples in the wells.

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 diluted further 10 time i.e. 1/100x1/10 = 1/1000 micromol/ul which means 1nanomol/microlitre

1ul = 1 nanomol

2ul = 2 nano mol

10ul = 10 nanomol

I tried many different products to get better ATP measurements in Heart tissue of mice but failed then I bought abcam ATP Assay Kit (Colorimetric/Fluorometric) (ab83355) to measure ATP content in heart tissue of mcie which was knockout to PGC1 alpha, as recommended in their datasheets and I never had any problem with it. I got very important data which I used for my research article. I think its great kit to use and have everything in it. I think this is best product to detect ATP content.

Testing ab83355 kit in cell culture media

Good Excellent 5/5 (Ease of Use)
We are interested in cuantifying the amount of ATP released to the culture media from primary astrocytes and microglia BV2 after their treatment with different compounds. To that end, we collected the media (DMEM with 1% of penicilin/streptomicin and 4mM of L-glutamine, but without phenol red) and froze them in liquid nitrogen. When we proceeded with the quantification, we thawed the samples on ice and centrifuged them at 13,000 xg for 10 minutes, without applying any deproteinization step. After this, we went on with the assay. We tested the two methodologies available: colorimetric and fluorimetric. Using cells as positive control, we obtained signal by both procedures, but fluorimetric's was the most sensitive, with the hightest signal/background ratio.

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.
