  • Product overview

    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.

  • Notes

    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.

Functional Studies Use at an assay dependent dilution.


  • 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.

High background values in the fission yeast

Poor Average 3/5 (Ease of Use)
Two methods of sample preparation were tested.
1. Cell lysis by bead beating in acetyl-CoA assay buffer, deproteinization by 10 kDa spin column
2. Cell lysis by bead beating in TCA which also serves to denature proteins, neutralization by Na2CO3 to pH ~7
Extracts were prepared from fresh yeast biomass of S. pombe cells grown to exponential phase and processed as quickly as possible due to acetyl-CoA instability. Variable sample volumes in the assay - 5, 10 or 50 ul (samples diluted to 50 ul by assay buffer) were used. The standards and samples were measured in the 0-100 pmol range.

Figure legend:
A. Standard curve in the 0-100 pmol range. B. Fluorescence values of samples prepared from two yeast strains (A and B) using the 10kDa spin column. The acquired values of background samples (without conversion enzyme) are higher than those of samples. C. Fluorescence values of samples prepared from two yeast strains (A and B) using TCA precipitation. The acquired values of background samples is lower than those of samples only when 10 ul extract were used. Moreover, high volume (50 ul) of sample seems inhibitory for the assay.
