Growth regulated protein α (GRO-α), also known as CXCL1, is a chemokine that has mitogenic properties and is a neutrophil chemoattractant. GRO-α is secreted by macrophages, epithelial cells, neutrophils, and melanomas. GRO-α signals through the CXCR2 chemokine receptor and is important during spinal cord formation, inflammation, angiogenesis, tumorigenesis, and wound healing.

Activity Assay

Human GRO-α is fully biologically active when compared to standard. The activity is determined by the induced chemotaxis of human neutrophils.
