GRO beta/CXCL2, Human

-80°C

Human GRO-alpha, GRO-beta (MIP-2alpha), and GRO-gamma (MIP-2beta) are products of three distinct, nonallelichuman genes. GRO-beta and GRO-gamma share 90% and 86% amino acid sequence homology, respectively, with GROalpha. All three isoforms of GRO are CXC chemokines that can signal through the CXCR1 or CXCR2 receptors.GRO expression is inducible by serum or PDGF and/or by a variety of inflammatory mediators, such as IL-1 and TNF, in monocytes, fibroblasts, melanocytes and epithelial cells. In certain tumor cell lines, GRO is expressed constitutively.Similar to other alpha chemokines, the three GRO proteins are potent neutrophil attractants and activators. In addition, these chemokines are also active toward basophils.
Recombinant Human GRO beta/CXCL2 produced in E.coli is a single non-glycosylated polypeptide chain containing 74 amino acids. A fully biologically active molecule, rhGRO beta/CXCL2 has a molecular mass of 8.0 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
