詳細
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.
The endogenous catecholamines epinephrine and norepinephrine have profound effects on smooth muscle activity, cardiac function, carbohydrate and fat metabolism, hormone secretion, neurotransmitter release, and central nervous system actions. These activities are mediated by GPCRs belonging to two subfamilies, the α- and β-adrenoceptors (Bylund et al., 1994). The α2 adrenergic receptor subfamily members, consisting of α2A, α2B, and α2C, couple primarily to Gi to inhibit cAMP production, and play an important role in regulation of cardiovascular and CNS function. The α2A receptor at presynaptic sites has an inhibitory effect on catecholamine release from sympathetic nerve endings. Experiments with α2A -selective agonists and mice lacking α2A demonstrate that activation of α2A results in hypotension, sedation, analgesia, and hypothermia (Kable et al., 2000). Millipore′s cloned human α2A -expressing cell line is made in the Chem-1 host, which supports high levels of recombinant α2A 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 α2A.
