Product Description: Exodus-2, also known as CCL21, is a chemokine that is strongly produced in the human lymph nodes and spleen. Exodus-2 signals through the chemokine receptor CCR7 to regulate thymocyte and activated T cell migration. Exodus-2 also mediates the homing of lymphocytes to the lymphatic system. Human and mouse Exodus-2 proteins share greater than 85% amino acid sequence identity.
