Recombinant Human C-C motif chemokine 19 (CCL19)

Beta-chemokine exodus-3CK beta-11Epstein-Barr virus-induced molecule 1 ligand chemokine ; EBI1 ligand chemokine ; ELCMacrophage inflammatory protein 3 beta ; MIP-3-beta; Small-inducible cytokine A19

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 secondary lymphoid organs. Binds to chokine receptor CCR7. Recombinant CCL19 shows potent chotactic activity for T-cells and B-cells but not for granulocytes and monocytes. Binds to atypical chokine receptor ACKR4 and mediates the recruitment of beta-arrestin (ARRB1/2) to ACKR4.

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Beta-arrestin recruitment and G protein signaling by the atypical human chemokine decoy receptor CCX-CKR.Watts A.O., Verkaar F., van der Lee M.M., Timmerman C.A., Kuijer M., van Offenbeek J., van Lith L.H., Smit M.J., Leurs R., Zaman G.J., Vischer H.F.J. Biol. Chem. 288:7169-7181 (2013)

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
