The ChemiScreen LPA3 Lysophospholipid Receptor Stable Cell Line is an engineered cell line for use in studying drug candidates (small molecules or biologics) targeting GPCRs. This cell line enables assessment of ligand (e.g. LPA) based activation of LPAR3 GPCR activity via detection of increasing levels of intracellular calcium. The included cell line overexpresses LPAR3 alongside endogenous high levels of the promiscuous G protein, Gα15, coupling the receptor to the calcium signaling pathway. Upon activation of LPAR3, the resulting calcium activity can be fluorescently assayed. This stable modified cell line is provided as two vials of cryopreserved cells.
