About this item

Functional biotin labeled human CCL19 chemokine with very low endotoxin levels.

Extremely low endotoxin levels (<0.01 EU per 1 μg) Functional activity tested and validated For use in various streptavidin applications: Flow cytometry, microscopy, and other imaging techniques

Macrophage inflammatory protein-3-beta (MIP3β) (CCL19), also known as 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. Being a homeostatic chemokine, its primary physiological role is considered to be in the normal recirculation and homing of lymphocyte. However, MIP3β could also be proinfammatory, and is implicated in the post-HIV infection responses.
