General description
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.
Cholecystokinins are a series of peptides of heterogeneous length (5 to 58 amino acids) that are derived from preprocholecystokinin and are found in gastrointestinal tissues and the central nervous system. Gastrin is a related peptide with 5 C-terminal amino acids identical to those of cholecystokinin. Two GPCRs, CCK1 (CCKA) and CCK2 (CCKB), bind to CCK and/or gastrin to mediate the biological effects of the peptides. CCK2 binds to CCK and gastrin with similar affinity, whereas CCK1 selectively binds sulfated CCK. Binding of ligands to CCK2 stimulates mobilization of intracellular calcium by activation of Gq/11. In the periphery, CCK2 is present in the stomach, where it mediates gastrin-stimulated gastric acid secretion. In the CNS, CCK2 has been implicated in anxiety, depression, schizophrenia, depression and opioid analgesia (Noble et al., 1999). Millipore′s cloned human CCK2-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant CCK2 expression on the cell surface for functional detection via the calcium signaling pathway. Thus, the cell line is an ideal tool for screening for agonists, antagonists, and modulators at CCK2.
