线性范围:100nmol/L-3000nmol/L.Lysophosphatidic acid (LPA) is a phospholipid derivative that can act as a signaling molecule. LPA acts as a potent mitogen due to its activation of three high-affinity G-protein-coupled receptors called LPAR1, LPAR2, and LPAR3 (also known as EDG2, EDG4, and EDG7). Additional, newly identified LPA receptors include LPAR4 ,LPAR5 and LPAR6
