General description

Lyso-phosphatidylserine (lyso-PS) is produced by the enzymatic action of phospholipase A1 and A2 on phosphatidylserine.


Brain Lyso PS is suitable for use:
• as standard to quantify lipids using ultra high performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UHPLC-ESI-MS/MS)
• in the preparation of liposomes for coating dynabeads for binding of factor H (fH)
• as a ligand for G-protein coupled receptor 34 (GPR34) in in vitro experiments to investigate its effect granulosa cells(GC) and hormone production
• as substrate for sicariid phospholipase D (PLD) toxins (SicTox) enzymes

Biochem/physiol Actions

Lyso-Phosphatidylserine (Lyso-PS) plays a key role in histamine release from mast cells. Lyso-PS inhibits the growth to T cells. It is a chemotactic substance for fibroblast and tumor cells. Lyso-PS is involved in tumor progression and allergic reactions.
