Cytokines & Chemokines

Animal-Free Recombinant Human MCP-2 (CCL8) (Legacy Tebubio ref. 167AF-300-15). The MCP proteins are members of the CC chemokine family that signal through CCR2 and, with the exception of MCP-1, other CCR receptors. The MCP proteins chemoattract and activate monocytes, activated T cells, basophils, NK cells, and immature dendritic cells. The MCP family cross-reacts across species. Recombinant Human MCP-2 (CCL8) is an 8.9 kDa protein containing 76 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.

Animal-Free Recombinant Human Eotaxin (CCL11) (Legacy Tebubio ref. 167AF-300-21). Eotaxin is a CC chemokine that signals through the CCR3 receptor. It is produced by IFN-gamma-stimulated endothelial cells and TNF-activated monocytes. Eotaxin selectively chemoattracts eosinophils and, along with Eotaxin-2 and Eotaxin-3, plays a key role in the regulation of eosinophil recruitment in the asthmatic lung and in allergic reactions. Recombinant Human Eotaxin is an 8.3 kDa protein containing 74 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines.

Animal-Free Recombinant Human Leptin (Legacy Tebubio ref. 167AF-300-27). Encoded by the ob (obese) gene, Leptin is an adipose-derived cytokine that suppresses appetite and increases thermogenesis. Leptin exerts its anorectic effect via signaling through a hypothalamic receptor termed OB-R. Leptin has been shown to reduce body weight, food consumption, and plasma glucose levels in various in vivo models. Recombinant Human Leptin is a 16.0 kDa protein containing 147 amino acid residues.

Animal-Free Recombinant Human SDF-1alpha (CXCL12) (Legacy Tebubio ref. 167AF-300-28A). SDF-1alpha and beta are stromal-derived, CXC chemokines that signal through the CXCR4 receptor. SDF-1alpha and beta chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Additionally, the SDF-1 proteins exert HIV-suppressive activity in cells expressing the CXCR4 receptor. Human and murine SDF-1 proteins act across species. SDF-1alpha and beta contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1alpha protein is the result of alternative splicing of the SDF-1 gene and contains 68 amino acid residues. Recombinant Human SDF-1alpha is an 8.0 kDa protein containing 68 amino acid residues.

SDF-1alpha and beta contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1beta protein, produced by an N-terminal truncation of two additional amino acids, after removal of the signal sequence, contains 72 amino acid residues. Recombinant Human SDF-1beta is an 8.5 kDa protein containing 72 amino acid residues.
