  • 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.

Protocol:
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.

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...

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.
