Creative Proteomics has developed a reliable and reproducible method using highly sensitive GC/LC-MS/MS method for the rapid identification and quantification of endocannabinoids in different sample types, which can satisfy the needs of academic and industrial study in your lab.
Endocannabinoids are a family of lipid messengers present in a wide range of living organisms. In the brain, they regulate ion‐channel activity and neurotransmitter release critical to biological processes such as synaptic plasticity and learning and memory. Endocannabinoids are embedded within an intricate network of lipid pathways, the regulation of which controls the strength and duration of their signaling. Therefore, physiological, pathological, or pharmacological perturbations of these interconnected lipid pathways have a profound effect on the regulation of endocannabinoid signaling.

The recent development of high‐sensitivity and high‐throughput analytical tools affords a broader view of the endocannabinoid system, allowing researchers to place individual endocannabinoid molecules in the context of the interconnected network of their precursors and derivatives. Targeted lipidomics provides new opportunities for understanding endocannabinoid metabolism.
Gas chromatography (GC) has been widely used to separate endocannabinoid metabolites in lipid extracts from biological samples. GC is most often coupled with MS for sensitive detection and quantification of the analytes. In liquid chromatography- (LC-) based analysis of endocannabinoid metabolites, the stationary phase is usually reverse phase.

Because of their low abundance and structural variability, the quantification of endogenous endocannabinoid is challenging. With years of experience in lipidomics analysis services, Creative Proteomics has a good reputation in supporting the detection and quantification of a variety of lipids. Based on a highly stable, reproducible and highly sensitive separation, characterization, identification and quantitative analysis system, combined with GC/LC-MS/MS, we provide reliable, fast and cost-effective endocannabinoids analysis services.
