SAG-d8 contains eight deuterium atoms at the 5, 6, 8, 9, 11, 12, 14, and 15 positions. It is intended for use as an internal standard for the quantification of SAG by GC- or LC-mass spectrometry. Many protein kinase C -PKC) isoforms require activation via second messengers including Ca2+, diacylglycerol -DAG), and/or a phospholipid in order to phosphorylate target proteins, initiating a variety of important signaling cascades. 1-Stearoyl-2-arachidonoyl-sn-glycerol -SAG) is a DAG that contains the .omega.-6 polyunsaturated fatty acid arachidonic acid in the sn-2 position and stearic acid in the sn-1 position of the glycerol backbone. It can potently activate PKC.alpha., .epsilon., and .delta. at nM concentrations. Independent of PKC signaling, SAG competitively binds to the Ras activator RasGRP with a Ki value of 4.49 uM in Jurkat T-cells.
