It acts as an effective chemoattractant and neutrophil activator. CXCL7 interacts with its receptor C-X-C motif chemokine receptor 1/2 to promote tumor angiogenesis and tumor cell migration. Overexpression of the gene has been observed in peripheral blood cells of patients with renal cell carcinoma (RCC). Thus, it might be considered as a potent diagnostic marker for RCC._x000D_ Other Notes_x000D_ A sample Certificate of Analysis is available for this product._x000D_ Please type the word sample in the text box provided for lot number.
