Cytokines & Chemokines

Animal-Free Recombinant Human SDF-1beta (CXCL12) (Legacy Tebubio ref. 167AF-300-28B). 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-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.

Animal-Free Recombinant Human TECK (CCL25) (Legacy Tebubio ref. 167AF-300-45). TECK is a CC chemokine, specifically expressed by thymic stromal cells, and signals through the CCR9 receptor. TECK is chemotactic towards activated macrophages, thymocytes and dendritic cells. Recombinant Human TECK (CCL25) is a 14.2 kDa protein containing 127 amino acid residues, including the four conserved cysteine residues present in CC chemokines.

Animal-Free Recombinant Human I-TAC (CXCL11) (Legacy Tebubio ref. 167AF-300-46). I-TAC is a 'non-ELR' CXC chemokine that is regulated by interferon and signals through the CXCR3 receptor. I-TAC is chemoattractant for IL-2 activated T cells, but does not affect freshly isolated un-stimulated T cells, neutrophils, ormonocytes. Recombinant Human I-TAC (CXCL11) is an 8.3 kDa protein containing 73 amino acid residues, including the four highly conserved cysteine residues present in CXC chemokines.

Animal-Free Recombinant Human TWEAK (Legacy Tebubio ref. 167AF-310-06). TWEAK belongs to the TNF family of ligands, and signals through TWEAKR, also known as TNFRSF12A. TWEAK is expressed in a variety of tissues, including the adult heart, pancreas, skeletal muscle, small intestine, spleen and peripheral blood lymphocytes. TWEAK has the ability to induce NF-kappaB activation and chemokine secretion, and to exert an apoptotic activity in certain cells, such as HT-29 human adenocarcinoma cells when cultured in the presence of IFN-gamma. TWEAK also promotes proliferation and migration of endothelial cells. The human TWEAK gene encodes for a 249 amino acid type II transmembrane protein, which contains a 21 amino acid cytoplasmic domain, a 21 amino acid transmembrane domain, and a 207 amino acid extracellular domain. Recombinant Human TWEAK is a soluble 17.0 kDa polypeptide (154 amino acid residues) comprising the TNF-homologous region of TWEAK, and is generated by proteolytic processing of

Animal-Free Recombinant Murine TNF-alpha (Legacy Tebubio ref. 167AF-315-01A). TNF-alpha is a pleiotropic pro-inflammatory cytokine secreted by various cells, including adipocytes, activated monocytes, macrophages, B cells, T cells and fibroblasts. It belongs to the TNF family of ligands, and signals through two receptors, TNFR1 and TNFR2. TNF-alpha is cytotoxic to a wide variety of tumor cells, and is an essential factor in mediating the immune response against bacterial infections. TNF-alpha also plays a role in the induction of septic shock, autoimmune diseases, rheumatoid arthritis, inflammation, and diabetes. Human and murine TNF-alpha demonstrate significant cross-species reactivity. TNF-alpha exists in two forms; a type II transmembrane protein, and a mature soluble protein. The TNF-alpha transmembrane protein is proteolitically cleaved to yield a soluble, biologically active, 17 kDa TNF-alpha, which forms a non-covalently linked homotrimer in solution.
