C-X-C chemokine receptor type 4 (CXCR4) is an alpha-chemokine receptor specific for stromal-derived-factor-1 (SDF-1 also called CXCL12), a molecule endowed with potent chemotactic activity for lymphocytes. This receptor is one of several chemokine receptors that HIV isolates can use to infect CD4+ T cells. CXCR4 stands out for its pleiotropic roles in both physiological and pathological conditions and it represents a crucial target in drug development. CXCL12 is the principal CXCR4 specific ligand and that the pro-inflammatory chemokine macrophage migration inhibitory factor (MIF) is also able to bind and activate CXCR4.

| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing 50 mM Tris-HCl, 100 mM Glycine, pH7.5. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, Lyophilized powders are shipping with blue ice. Solutions are shipping with dry ice. |
