  • 产品概述

    Abcam's PicoProbe Acetyl CoA Assay Kit is a highly sensitive assay for determining Acetyl CoA level in a variety of biological samples. In the assay, free CoA is quenched then Acetyl CoA is converted to CoA. The CoA is reacted to form NADH which interacts with PicoProbe to generate fluorescence (Ex=535/Em=587 nm). The assay can detect 10 to 1000 pmol of Acetyl CoA (with detection limit ~0.4 µM) in a variety of samples.

  • 说明

    Acetyl CoA is a central molecule of metabolism. It carries acetate, used in the build-up and breakdown of larger molecules. Acetyl CoA is key in synthetic pathways leading to sesquiterpenes, precursors to cholesterol and other sterols, flavenoids and other polyketides, polyenes and long-chain fatty acids. It is the source of the acetyl group used in histone acetylation. The acetyl group is also incorporated into a variety of other molecules such as acetylcholine, melatonin, heme and TCA cycle intermediates.

  • Examples of standard curves generated following the ab87546 kit protocol.
  • Induction of acetyl-CoA in mitochondria by palmitate. Mitochondria were isolated from cells after palmitate treatment (300 μM) at 1, 4 and 16 h, and then used in the concentration assay of acetyl-CoA. 

    The acetyl-CoA content was determined immediately after isolation of the mitochondria using ab87546. Briefly, acetyl-CoA standard curve was made in the range of 0–100 pM and the correlation coefficient was 0.990 or higher. Protein was removed in the sample using the perchloric acid protocol and the supernatant was neutralized with 3 M KHCO3. The CoASH Quencher and Quencher remover were added into the sample to correct the background generated by free CoASH and succ-CoA. The sample was then diluted with the reaction mix, and the fluorescence signal was measured at Ex/Em = 535/589 nm with Spectra max Gemini XPS (Molecular Devices, Sunnyvale, CA). The relative acetyl-CoA concentration was normalized with the mitochondrial protein.

J’ai contacté le laboratoire concernant le kit ab87546 :

1.Nous recommandons d’utiliser ˜2-5 X 10^6 cellules pour chaque manip.

2. Il est recommandé de faire une déprotéinisation pour des cellules en culture. J’ai attaché ...

I discussed this with the laboratories. They confirmed that the sample can be stored at -80 degree centigrade once prepared. However, we recommend to use the sample immediately after preparation for maximum efficiency.

In principle, eliminating the quenching and conversion step will allow you to measure CoA alone. However, the kit was not produced nor validated for this purpose, so we cannot guarantee that it will work, nor do we have a CoA standard that has been val...

I am happy to confirm that kit PicoProbe Acetyl CoA Assay Kit (ab87546) can be used with frozen mouse tissues.

Please find a protocol for tissue preparation below:

1. Tissue samples: (20 - 1000 mg) should be frozen rapidly (liqui...

The ab138889 CoA detection kit assay buffer is 100 mM Na phosphate buffer, pH = 6. The RIPA buffer may be an issue with the other two kits, since they are enzyme-based, and that kind of assay is generally incompatible with detergents. Your best approac...

It is not the best case scenario to freeze samples repeatedly before performing the assay. However, if you need to freeze the samples, it would be possible after separating the sample from the KClO4 pellet.


I have contacted the lab and unfortunately, this is only a fluorometric assay kit and cannot be used colorimetrically.

Thank you for contacting us.

This kit is actually based on reaction of breakdown of Acety-CoA into CoA and acetyl group. This is inverse to what you are looking for. The kit have enzyme which actualy breakdown acetyl CoA rather than synthesizi...
