Reconstitution Reconstitute the lyophilized recombinant Human Granulocyte Chemotactic Protein-2/CXCL6 (CHO-expressed) (rHuGCP-2/CXCL6) to 100 μg/mL using ddH2O or PBS. Storage & Stability Lyophilized recombinant Human Granulocyte Chemotactic Protein-2/CXCL6 (CHO-expressed) (rHuGCP-2/CXCL6) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Human granulocyte chemotactic protein 2 (GCP-2)/CXCL6 is an ELR-positive CXC chemokine with a length of 77 amino acids. CXCL6 is a CXC chemokine expressed by macrophages and epithelial and mesenchymal cells during inflammation. In killed bacteria, GCP-2/CXCL6 associates with bacterial surfaces, which showed membrane disruption and leakage. In the case of leukocytes, GCP-2/CXCL6 binding to the receptors causes cellular activation, chemotaxis, and sometimes, depending on the context, execution of cytotoxic effector functions. Activation of endothelial cells by GCP-2/CXCL6 causes a mitogenic response, resulting in angiogenesis[1]. |
