Recombinant Human CXCL1

Chemokine (C-X-C motif) ligand 1 (CXCL1) is a small cytokine with mitogenic properties belonging to the CXC chemokine family that was previously called GRO1 oncogene, GROα, KC, Neutrophil-activating protein 3 (NAP-3) and melanoma growth stimulating activity, alpha (MSGA-α).¹ CXCL1 is expressed by macrophages, neutrophils and epithelial cells.² CXCL1 plays a role in spinal cord development by inhibiting the migration of oligodendrocyte precursors and is involved in the processes of angiogenesis, inflammation, wound healing.^3,4

The biological activity of Human GRO/MGSA was determined by its ability to induce myeloperoxidase release from cytochalasin treated neutrophils (Schröder, J. et al., 1987, J. Immunol. 139:3474), or chemotaxis of mouse BaF/3 cells transfected with hCXCR2. The expected ED₅₀ for these effects are typically 0.15 - 0.3 μg/ml or 1 - 4 ng/ml, respectively.

Lyophilized

The predicted molecular weight of Recombinant Human CXCL1 is Mr 7.9 kDa.

7.9

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.
