Recombinant Human CCL19, biotinylated

May play a role not only in inflammatory and immunological responses but also in normal lymphocyte recirculation and homing. May play an important role in trafficking of T-cells in thymus, and T-cell and B-cell migration to sPubMed:9498785}.

12 months from date of receipt, -20°C to -70°C, as supplied. 1 month,- 20°C to -70°C, under sterile conditions after reconstitution. Best if used immediately after reconstitution. Avoid multiple freeze-thaw cycles.

CCL19 (also known as Macrophage Inflammatory Protein-3beta, MIP-3b, and EBI1 ligand chemokine, ELC) directs chemotaxis of dendritic cells and certain B- and T-lymphocytes, but not monocytes or granulocytes. It is constitutively expressed in thymus and lymph nodes and binds specifically to target cells expressing the receptor CCR7. As a homeostatic chemokine, its primary physiological role is thought to be in the normal recirculation and homing of lymphocytes. However, CCL19 can also be proinflammatory and is implicated in post-HIV infection responses.
