Description
Description: Patent pending PCT/EP2021/068386Capitainer®B Vanadate is based on the technology of Capitainer® B. In addition, it incorporates our proprietary technology for integrating the phospholipase D (PLD) inhibitor sodium metavanadate (NaVO3) in the DBS paper disc.Enables accurate testing of Phosphatidylethanol (PEth)Eliminates the risk of post sampling PEth formationShipping and storage of the sample in ambient temperatureVolumetric, solves the problem with traditional DBSEnables easier sampling via finger bloodCapitainer® B Vanadate is the only volumetric microsampling device scientifically shown to enable accurate PEth testing without risk of post sampling formation [1]. About phosphatidylethanol (PEth)PEth is found in red blood cells and is an abnormal phospholipid that is formed in the presence of ethanol. It is formed via a transphosphatidylation reaction of phospholipase D (PLD). PEth accumulates with frequent alcohol consumption with a half-life of approximately 4 days and is therefore a marker for long term alcohol use.In blood that contains ethanol at sampling, PEth may continue to form after sampling [2] leading to falsely elevated concentrations. A well-known problem in venous blood samples were storage temperature and shipping conditions need to be controlled to limitit In Vitro formation. Formation of PEth can be stopped through inhibiting the PLD activity. Sodium metavanadate (NaVO3) is an effective PLD inhibitor.We recommend reading the full publication of Beck et al.
