产品说明

一般描述

In biochemical signaling, diacylglycerol (DAG) functions as a second messenger signaling lipid, and is a product of the hydrolysis of the phospholipid PIP2 (phosphatidylinositolbisphosphate) by the enzyme phospholipase C (PLC) (a membrane-bound enzyme) that, through the same reaction, produces inositol trisphosphate (IP3). Although inositol trisphosphate (IP3) diffuses into the cytosol, DAG remains within the plasma membrane due to its hydrophobic properties. IP3 stimulates the release of calcium ions from the smooth endoplasmic reticulum, whereas DAG is a physiological activator of protein kinase C (PKC). The production of DAG in the membrane facilitates translocation of PKC from the cytosol to the plasma membrane.
Diacylglycerol mimicks the effects of the tumor-promoting compounds phorbol esters.
1,2-dimyristoyl-sn-glycerol (14:0 DG) with small polar headgroup and two fatty acid, is an E coli membrane lipid.

应用

14:0 DG may be used:

  • in the reconstitution of dry lipids for thin layer chromatography
  • in lipid nanoparticles for RNA delivery studies
  • as a standard in gas chromatography–mass spectrometry (GC-MS) analysis for the quantification of lipid A diacylglycerols

生化/生理作用

Diacylglycerol (DAG) displays a flip-flop motion. This movement of DAG is inhibited by membrane protein integrase (mini-MPIase-3).It also forms nonlamellar phase.

储存及稳定性

Diacylglycerols are conveniently stored in chloroform solutions in glass vials with PTFE-lined caps at -20℃. Under these conditions acyl migration is minimal. Avoid plastic when handling chloroform solutions.

其他说明

Effective concentration:
Most biological responses saturate at 20 to 250 μM sn-1,2-dioctanoylglycerol. Only sn-1,2 isomers appear to be active.
Delivery to cells:
Dry samples of diacylglycerol in chloroform, using a stream of nitrogen. Dissolve the residue in an appropriate volume of ethanol or DMSO, then dilute to the desired aqueous medium.
Precaution: Since short chain Diacylglycerols mimic effects of the tumor-promoting phorbol diesters in a number of biological systems, extra care should be employed in their handling. Treatment of solutions, vessels and other articles with 1N NaOH before washing or discarding will destroy diacylglycerols.
