Ready-to-Assay TP Prostanoid Receptor Frozen Cells

Millipore′s Ready-to-Assay GPCR frozen cells are designed for simple, rapid calcium assays with no requirement for intensive cell culturing. Millipore has optimized the freezing conditions to provide cells with high viability and functionality post-thaw. The user simply thaws the cells and resuspends them in media, dispenses cell suspension into assay plates and, following over night recovery, assays for calcium response.

TP receptors (Thromboxane A2 receptors) are widely distributed among different organ systems and have been localized on both cell membranes and intracellular structures. TP receptors belong to G protein-coupled receptor family (Hirata et al., 1991). Activation of TP receptors induces platelet aggregation, vascular and respiratory smooth muscle constriction, and enhances mitogenic responses of vascular smooth muscle cells that are stimulated by growth factors (Ali et al., 1993; Hanasaki et al., 1990). The human TP receptor is encoded by a single gene that is alternatively spliced at the carboxyl terminus, resulting in two isoforms, TPα (343 residues) and TPα (407 residues). Both isoforms couple to Gq pathway, but couple oppositely to adenylate cyclase. Millipore′s cloned human TP-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant TP expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for agonists, antagonists, and modulators at TP.
