Ready-to-Assay CCR7 Chemokine 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.

CCR7 is a GPCR that binds to CC chemokine ligands MIP-3β (ELC/CCL19) and 6Ckine (CCL21) (Yoshiida et al., 1997). These ligands are expressed in the secondary lymphoid organs, and binding to CCR7 expressed in naïve T cells, B cells and dendritic cells directs migration of these cells to sites of antigen presentation (Forster et al., 199(. Inhibition of CCR7/ligand interactions inhibits contact sensitivity, delayed type hypersensitivity, and graft vs host disease in experimental models (Forster et al., 1999; Sasaki et al., 2003). In addition, CCR7 expression by breast cancer, melanoma, and other malignant cells are associated with lymph node metastasis (Muller et al., 2001; Payne and Cornelius, 2002). Millipore′s cloned human CCR7-expressing cell line is made in the Chem-1 host, which supports high levels of recombinant CCR7 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 CCR7.
