Beschreibung

Allgemeine Beschreibung

This stable-labeled internal standard is suitable for quantitation of PEth 16:0/18:1 in LC/MS or GC/MS applications. PEth 16:0/18:1, also known as phosphatidylethanol 16:0/18:1, is a sensitive and specific biomarker for alcohol use and abuse. Since the detection window of PEth 16:0/18:1 in blood is longer than that of ethyl glucuronide (EtG) or ethyl sulfate (EtS) in urine, measurement of blood PEth 16:0/18:1 level is routinely performed in clinical toxicology and forensic testing applications such as abstinence monitoring and workplace drug testing. PEth 16:0/18:1 has also been investigated as a biomarker to confirm prenatal alcohol exposure (PAE).

Anwendung

• Validation of LC-MS/MS method for erythrocyte phosphatidylethanol: A recent study validated a liquid chromatography tandem mass spectrometry method for erythrocyte phosphatidylethanol (PEth), utilizing the PEth 16:0/18:1-D₅ internal standard. This research highlights critical considerations for using PEth as a reliable clinical biomarker of alcohol consumption, proving essential for advancements in biochemical research reagents and methodology (White et al., 2022).
