Recombinant Mouse CXCL5

CXCL5 is an inflammatory chemokine that belongs to the CXC chemokine family¹ that has a role in the development of cardiovascular diseases.² CXCL5 is expressed by fibroblasts, is induced by bacterial lipopolysaccharides, and is chemotactic for neutrophils.¹ It is expressed by epithelial cells within colorectal mucosa is a chemoattractant for neutrophils and has been implicated in Crohn's disease and ulcerative colitis.³ CXCL5 is important in growth and development of colorectal cancer, implicating a future role in both cancer therapy and diagnosis.⁴

The biological activity of Mouse LIX was determined by its ability to induce myeloperoxidase release from cytochalasin-B treated human neutrophils (Schröder, J.M. et al., 1987, J. Immunol. 139:3474), or chemotaxis of Baf/3 hCXCR-2 transfected cells. The expected ED₅₀ for this effect is typically 1 - 3 μg/ml or 0.03 - 0.1 μg/ml, respectively.

Lyophilized

The predicted molecular weight of Recombinant Mouse CXCL5 is Mr 8 kDa.

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

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.
