The antibody was purified by affinity chromatography and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
Human CCX-CKR, also known as CCRL1, is a 40 kD, G-protein-coupled, seven transmembrane receptor. CCRL1 is a decoy receptor for CCL2, CCL8, CCL13, CCL19, CCL21 and CCL25 that regulates chemotaxis of lymphocytes and cancer cells. Chemokine binding by CCX-CKR causes its internalization, reducing levels of available chemokine, and thus regulating migration of lymphocytes and cancerous cells. CCX-CKR is expressed by stromal cells of skin-draining lymph nodes, thymic epithelial cells, and immature dendritic cells (DCs). A low CCX-CKR expression in tumor cells correlates with a poor survival rate of breast cancer patients.
