Cytokines & Chemokines

Recombinant Viral MIP-2 (Legacy Tebubio ref. 167350-03). Viral MIP-2 (vMIP-2) is a chemokine analog encoded by the human herpes virus, and has been shown to have antagonist activity towards several chemokine receptors. Recombinant Viral MIP-2 is a 7.9 kDa protein consisting of 70 amino acids, including the four highly conserved cysteine residues present in CC chemokines.

Recombinant Rat IL-1alpha (Legacy Tebubio ref. 167400-01A). IL-1a is a non-secreted, proinflammatory cytokine produced in a variety of cells, including monocytes, tissue macrophages, keratinocytes, and other epithelial cells. Both IL-1a and IL-1b bind to the same receptor and have similar, if not identical, biological properties. These cytokines have a broad range of activities including the stimulation of thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, mitogenic FGF-like activity, and the release of prostaglandin and collagenase from synovial cells. However, whereas IL-1b is a secreted cytokine, IL-1a is predominantly a cell-associated cytokine. Recombinant Rat IL-1a is a 17.7 kDa protein containing 155 amino acid residues.

However, whereas IL-1b is a secreted cytokine, IL-1a is predominantly a cell-associated cytokine. Recombinant Rat IL-1b is a 17.4 kDa protein containing 153 amino acid residues.

Recombinant Rat IL-1beta (Legacy Tebubio ref. 167400-01B). IL-1b is a proinflammatory cytokine produced in a variety of cells, including monocytes, tissue macrophages, keratinocytes, and other epithelial cells.

Recombinant Rat IL-3beta (Legacy Tebubio ref. 167400-03). IL-3 is a hematopoietic growth factor that promotes the survival, differentiation and proliferation of committed progenitor cells of the megakaryocyte, granulocyte-macrophage, erythroid, eosinophil, basophil and mast cell lineages. Produced by T cells, mast cells and eosinophils, IL-3 enhances thrombopoiesis, phagocytosis, and antibody-mediated cellular cytotoxicity. Its ability to activate monocytes suggests that IL-3 may have additional immunoregulatory roles. Many of the IL-3 activities depend upon co-stimulation with other cytokines. IL-3 is a species-specific, variably glycosylated cytokine. Recombinant Rat IL-3beta is a 16.3 kDa globular protein containing 144 amino acid residues.

Recombinant Rat IL-4 (Legacy Tebubio ref. 167400-04). IL-4 is a pleiotropic cytokine that regulates diverse T and B cell responses including cell proliferation, survival and gene expression. Produced by mast cells, T cells and bone marrow stromal cells, IL-4 regulates the differentiation of naive CD4+ T cells into helper Th2 cells, characterized by their cytokine-secretion profile that includes secretion of IL-4, IL-5, IL-6, IL-10, and IL-13, which favor a humoral immune response. Another dominant function of IL-4 is the regulation of immunoglobulin class switching to the IgG1 and IgE isotypes. Excessive IL-4 production by Th2 cells has been associated with elevated IgE production and allergy. Recombinant Rat IL-4 is a 14.0 kDa globular protein containing 126 amino acid residues.
