Macrophage Inflammatory Protein-3 beta (CCL19), mouse recombinant (rmMIP-3b)

Protein function: Strongly chemotactic for naive (L-selectinhi) CD4 T- cells and for CD8 T-cells and weakly attractive for resting B- cells and memory (L-selectinlo) CD4 T-cells. May play a role in promoting encounters between recirculating T-cells and dendritic cells and in the migration of activated B-cells into the T-zone of secondary lymphoid tissues. Specifically binds to chemokine receptor CCR7. [The UniProt Consortium]
