    Product Description

    1-Octadecyl-2-hydroxy-sn-glycero-3-phosphate (1-Octadecyl LPA) is a LPA analog containing stearyl alcohol at the sn-1 position. LPA binds to one of five different G protein-linked receptors to mediate a variety of biological responses including cell proliferation, smooth muscle contraction, platelet aggregation, neurite retraction, and cell motility.1,2 Alkyl ether-linked LPA derivatives have a higher platelet aggregating activity than the acyl derivatives, most likely stemming from an alkyl-specific LPA receptor. For example, 1-octadecyl LPA has platelet aggregating activity with an EC50 value of 9 nM versus an EC50 value of 177 nM for 1-octadecanoyl LPA.3

    WARNING This product is not for human or veterinary use.
