Advantages of DSPA

  • As a part of the double membrane, DSPA is used to study its role in the formation of vesicle lysis, particularly with the influence on factors associated with coat protein I (COPI). 

  • DSPA is also utilized to investigate its impact on the changes in calcium ion (Ca2+) concentration within C6 rat glioma and L2071 mouse fibroblasts. 

  • DSPA is additionally used to explore its effects on the phosphorylation of cytochrome b (558)-alpha chain (also known as p22phox). 

DSPA Product Properties

DSPA acts as a biosynthetic precursor for producing membrane glycerophospholipids and triacylglycerols, participates in the regulation of the mammalian target of rapamycin (mTOR) pathway, and is involved in membrane transportation, primarily via membrane fusion and fission.
