Recombinant Human CXCL2
Pricing & Details
Chemokine (C-X-C motif) ligand 2 (CXCL2), also known as MIP2-α and GROβ, is a small, inducible cytokine belonging to the CXC chemokine family. Other chemokines in this group include IL-8, GROα, GROγ, mouse KC, ENA78, GCP2 and PBP/CTAPIII/β TG/NAP2. Since it is structurally related to IL-8, CXCL2 competes with IL-8 for binding to IL-8 receptors on neutrophils and to a lesser extent, basophils. CXCL2 is involved in attraction of polymorphonuclear granulocytes to sites of infection (1). It is active against Gram-negative (Escherichia coli) and Gram-positive (Staphyllococcus aureus) bacteria. It is secreted by monocytes and macrophages and is chemotactic for hematopoietic stem cells (2-4). MMP-12 cleaves CXCL2 at the ELR sequence motif, which is known to be the critical receptor binding motif leading to the loss of chemotactic activity (5).
>97% by SDS-PAGE and analyzed by silver stain.
<0.1 EU/µg as determined by the LAL method
The biological activity of Human GRO-Beta was determined by by its ability to induce myeloperoxidase release from cytochalasin B treated neutrophils (Schröeder, J. et al., 1987, J. Immunol. 139:3474), or chemotaxis of hCXCR2 transfected mouse BaF/3 cells. The expected ED50 for these effects are typically 0.3 - 0.9 μg/ml, or 3 - 15 ng/ml, respectively.
