Acyl CoAs Analysis Service

Acyl-CoAs are essential for many physiological processes, like lipid synthesis, fatty acid oxidation, ketone body generation, xenobiotic metabolism, and signaling transduction. Generally speaking, acyl-CoAs like free CoA, acetyl-CoA, and malonyl-CoA assist in regulation of metabolic flux. For example, glycolysis and fatty acid oxidation are regulated by the ratio of acetyl-CoA to free CoA. Another example is that the elevation of malonyl-CoA will lead to the synthesis of fatty acids and thereby inhibiting fatty acid oxidation by preventing acyl-CoA going into the mitochondrion. What’s more, the deacylation and acylation caused by various acyl-CoAs, like acetyl-CoA, palmitoyl-CoA and succinyl-CoA, plays an essential role in the function regulation of many proteins and genes. Acting as allosteric regulators of several enzymes and proteins, acyl-CoAs have a central role in many basic pathways.

However, there are various kinds of acyl-CoAs in the cell and may involve many other compounds besides fatty acids and their oxidized derivatives. Acyl-CoAs only exist inside the cells and their profiling inside the cells can give you some clues of the local metabolic status. Since each organ exerts its specific function and has its specific energetic demand, each organ is therefore expected to show a different acyl-CoA profile. For example, to meet the ATP demand for heart contraction, the heart tissue prefers utilizing fatty acids. However, in the brain, glucose and ketone bodies are primary substrate for energy generation. Meantime, in the liver, both the oxidation and synthesis of fatty acid are highly active. The profiles of the acyl-CoAs of these tissues broadly reveal the energy source preferences of these organs.

The need for a method to extract, separate, and quantify various amounts variety of acyl-CoAs with limited amounts of biological material increasing dramatically. Numerous methods have been developed to meet the requirement to measure acyl-CoAs in different biological tissues. Quantitative profiling of acyl-CoAs is a huge challenge for analytical world. This is because there are various kinds of acyl-CoAs and their concentrations in different tissues are in a wide range. What’s more, the wide range of polarity of the acyl-CoAs poses a challenge for LC method development. Though alkaline mobile phases can be used to improve the shapes of acyl-CoAs, their application is harmful to silica-based C18 columns and dramatically shortens the lifespan. Most methods, only analyze one kind of acyl-CoAs, short-, medium-, or long-chain. So far, MS is the most sensitive and reliable method for acyl-CoAs studies. Various LC-MS/MS approaches have been developed to enhance the sensitivity. Based on the fragmentation pattern, a MRM method allows the selection of both precursor and product ions and thereby ensure quantitatively profile of Acyl-CoAs with high sensitivity and accuracy.

From Our Clients

"I recently used their proteomics service for a project analyzing protein interactions in yeast models. The team was very responsive and helped clarify the methodology they employed, which made me feel confident in the results. The data quality was solid, with clear identification of several key proteins involved in our study. Their thorough analysis enabled me to pinpoint specific interactions that I hadn't considered before, which significantly improved the direction of my research. I appreciate their professionalism and support throughout the process."

Sarah Thompson, University of California, Berkeley

"Our lab collaborated with them on a project studying cancer biomarkers. The proteomics analysis provided was detailed and focused, specifically highlighting the differential expression of proteins between healthy and tumor samples. Their clear explanations of the data helped my team understand the biological implications. I also appreciated their willingness to revise the reports based on our feedback, ensuring that we had everything we needed for our publication. This collaborative spirit was invaluable."

Emily Rodriguez, Stanford University

"Our lab worked with them on a project studying the effects of diet on gut microbiota using proteomics. They used a label-free quantification method to analyze proteins in fecal samples before and after dietary intervention. The results showed significant changes in protein expression linked to microbial activity. This was pivotal for our hypothesis about diet-microbiota interactions. The clarity of their data presentation made it easy for our team to integrate these findings into our ongoing research."

Dr. Lisa Wong, University of Toronto

"My experience with Creative Proteomics during the mass spectrometry analysis was excellent. We sent in human saliva and mouse brain tissue samples, which they expertly analyzed using both LC-MS and GC-MS techniques. The results were invaluable, revealing key metabolites in the saliva and identifying biomarkers linked to brain function in the brain tissue."

Dr. Emily Carter, Senior Research Scientist

"The overall service from Creative Proteomics was outstanding. They made the entire process seamless and efficient, allowing us to focus on our research. We worked with leaf and root samples from various Arabidopsis genotypes for targeted metabolomics analysis. Their thorough profiling of primary and secondary metabolites gave us important insights into how the plants respond metabolically to environmental stress."

Dr. Laura Henderson, Plant Physiologist

"We had a pleasant collaboration with Creative Proteomics on mass spectrometry analysis of lipids. They conducted a detailed analysis of lipid species, providing us with important insights into lipid metabolism and its relationship with metabolic syndrome disease states."
