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.

Vasoactive intestinal peptide (VIP), a 28 amino acid peptide originally isolated by its vasodilation activity, binds to two class B GPCRs, VPAC1 and VPAC2, to exert its functions in the CNS, vasculature, immune system and adrenal medulla (Harmar et al., 1998). In the immune system, VPAC2 is expressed on stimulated CD4 T cells, and binding of T cell-derived VIP to VPAC2 induces a shift toward the Th2 pathway (Delgado et al., 2004; Voice et al., 2004). In addition, VPAC2 is an essential regulator of the circadian pacemaker of the hypothalamic suprachiasmatic nuclei (Hughes et al., 2004). Milliproe′s cloned human VPAC2-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant VPAC2 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 antagonists of interactions between VPAC2 and its ligands.
