Recombinant Human CXCL3

Chemokine (C-X-C motif) ligand 2 (CXCL2) is an inducible murine chemokine involved in attraction of polymorphonuclear granulocytes to sites of infection.¹ This chemokine is secreted by monocytes and macrophages and is chemotactic for hematopoietic stem cells.^2,3,4

The biological activity of Human GRO-gamma was determined by its ability to induce myeloperoxidase release from cytochalasin B treated neutrophils (Shröeder, J. et al., 1987, J. Immunol. 139:3474) or chemotaxis of BaF/3 hCXCR-2 transfected cells. The expected ED₅₀ for these effects are typically 0.1 - 0.3 μg/ml or 2 - 10 ng/ml, respectively.

Lyophilized

The predicted molecular weight of Recombinant Human CXCL3 is Mr 8 kDa.

This recombinant protein was lyophilized from a 0.2 μm filtered solution in 35% acetonitrile (CH₃CN) and 0.1% trifluoroacetic acid (TFA).

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
