1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PC is intended for use as an internal standard for the quantification of 1-palmitoyl-2-hydroxy-sn-glycero-3-PC (Item No. 10172) by GC- or LC-MS. 1-Palmitoyl-2-hydroxy-sn-glycero-3-PC is the ubiquitous lipid species generated following phospholipase A2 (PLA2) hydrolysis of phosphatidylcholine.{11139} It increases the production of reactive oxygen species (ROS) and decreases superoxide dismutase (SOD) and endothelial nitric oxide synthase (eNOS) protein levels and phosphorylation of ERK1/2 in human umbilical vein endothelial cells (HUVECs) when used at a concentration of 125 uM.{42919} 1-Palmitoyl-2-hydroxy-sn-glycero-3-PC potentiates the secretion of IL-6, IL-1B, IL-12, and TNF-a in LPS-stimulated M1 macrophages, but has no effect on CD163, CD206, CD36, or IL-10 in LPS-stimulated M2 macrophages when used at concentrations of 0.3 and 1.0 uM.{42920} It increases TGF-B1 production and enhances Foxp3 protein levels in Treg cells in isolated human peripheral blood when used at a concentration of 10 uM.{42921} 1-Palmitoyl-2-hydroxy-sn-glycero-3-PC enhances neutrophil function, bacterial clearance, and survival in mouse models of sepsis when administered at a dose of 10 mg/kg.{11693} 1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PC MaxSpec standard is a quantitative grade standard of 1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PC (Item No. 28153) that has been prepared specifically for mass spectrometry and related applications where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This 1-Palmitoyl-d9-2-hydroxy-sn-glycero-3-PC MaxSpec standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.
