Biolegend, 353209, Pacific Blue™ anti-human CD197 (CCR7) Antibody, 25tests

CCR7, also known as CD197, is a chemokine receptor that binds CCL19 and CCL21. CCR7 and its ligands link innate and adaptive immunity by affecting interactions between T cells and dendritic cells and their downstream effect. Naïve T cells enter the lymph node through high endothelial venules, which express CCL21. Dendritic cells and macrophages enter the lymph node through afferent lymphatics. The encounter of T cells and dendritic cells in the T cell zone is CCR7-dependent. In addition, during immunological surveillance, B cells recirculate between B-cell-rich compartments (follicles or B cell zones) in secondary lymphoid organs, surveying for antigen. After antigen binding, B cells move to the boundary of B and T zones to interact with T-helper cells; this B cell migration is directed by CCR7 and its ligands. CCR7-positive cancer cell expression has been associated with lymph node metastasis.

Q: Does staining at room temperature or even at 37°C help for checking chemokine receptors expression?
A: Due to continuous recycling of many chemokine receptors, it may be worthwhile to consider staining at room temperature or at 37°C if the staining at lower temperature (which can potentially reduce receptor turnover) is not optimal.
