Human Il-3 Elisa Kit

Description: IL-6 is a pleiotropic cytokine that plays an important role in host defense by regulating immune and inflammatory responses. Produced by T cells, monocytes, fibroblasts, endothelial cells and keratinocytes, IL-6 has diverse biological functions. It stimulates B-cell differentiation and antibody production, synergizes with IL-3 in megakaryocyte development and platelet production, induces expression of hepatic acute-phase proteins, and regulates bone metabolism. IL-6 signals through the IL-6 receptor system that consists of two chains, IL-6R α and gp130. Murine IL-6 is inactive on human cells, while both human and murine are equally active on murine cells. Recombinant murine IL-6 is a 21.7 kDa protein containing 187 amino acid residues.

Description: IL-22 is a member of the IL-10 family of regulatory cytokines which includes IL-10, IL-19, IL-20, IL-22, IL-24 and IL-26. Members of this family share partial homology in their amino acid sequences, but they are dissimilar in their biological functions. Produced by T lymphocytes, IL-22 inhibits IL-4 production by Th2 cells, and induces acute phase reactants in the liver and pancreas. IL-22 signals through a receptor system consisting of IL-10R-β/CRF2-4 and IL-22R, both of which are members of the class II cytokine-receptor family. Recombinant murine IL-22 is a 33.4 kDa non-disulfide-linked homodimeric protein containing of two 146 amino acid polypeptide chains.

Description: IL-10 is an anti-inflammatory cytokine and a member of the IL-10 family of cytokines, which have indispensable functions in many infectious and inflammatory diseases. Mouse IL-10 Recombinant Protein is purified interleukin-10 produced in yeast.

Description: IL-13 is an important mediator of allergic inflammation and disease. In addition to effects on immune cells, IL-13 is implicated as a central mediator of the physiologic changes induced by allergic inflammation in many tissues. Equine IL-13 Recombinant Protein is purified interleukin-13 produced in yeast.

Description: Interleukin-6 (IL-6) is an interleukin that acts as both a pro-inflammatory and anti-inflammatory cytokine. Equine IL-6 Recombinant Protein is purified interleukin-6 produced in yeast.

Description: Interleukin-15 (IL-15) is a cytokine with structural similarity to IL-2 that is secreted by mononuclear phagocytes following infection by virus(es). This cytokine induces cell proliferation of natural killer cells. Swine IL-15 Recombinant Protein is purified interleukin-15 produced in yeast.

Description: IL-4 has many biological roles, including the stimulation of activated B-cell and T-cell proliferation, and the differentiation of CD4+ T-cells into Th2 cells. It is a key regulator in humoral and adaptive immunity. Equine IL-4 Recombinant Protein is purified interleukin-4 produced in yeast.

Description: Interleukin-2 (IL-2) is a cytokine produced by T-helper cells in response to antigenic or mitogenic stimulation. It is required for T-cell proliferation and other activities crucial to the regulation of the immune response. Equine IL-2 Recombinant Protein is purified interleukin-2 produced in yeast.

Description: Interleukin-8 (IL-8), also known as CXCL8, is an ELR-positive CXC family member chemokine produced by macrophages and other cell types such as epithelial cells. ELR-positive CXC chemokines such as IL-8 specifically induce the migration of neutrophils, and interact with chemokine receptors CXCR1 and CXCR2. Chicken IL-8 Recombinant Protein is purified interleukin-8 produced in yeast.

Description: Studies suggest that IL-21 is a key component of CD4 T cell help that is required for maintaining the CD8+ T cell responses and inducing B cell antibody response. It is also implicated in the development of autoimmune disease and has antitumor activity.

Description: Interleukin-1 Receptor Antagonist Protein (IL-1F3, IL-1ra) belongs to the IL-1 family of cytokines, whose members play key roles in the development and regulation of inflammation. IL-1 receptor antagonist (IL-1ra; IL-1F3) reduces inflammation by blocking the binding of the agonist receptor ligands. Dolphin IL-1 Receptor Antagonist Recombinant Protein is purified interleukin-1 receptor antagonist protein (IL-1F3, IL-1ra) produced in yeast.

Description: Interleukin-4 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 150 amino acids fragment (25-153) and having a total molecular mass of 17.2kDa.;The IL-4 is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Description: IL-6 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 204 amino acids fragment (30-212) and having a total molecular mass of 23.1kDa with a 20 aa N-terminal His tag. ;The IL-6 His is purified by proprietary chromatographic techniques.

Description: IL-1 beta (IL-1β) is a member of the interleukin 1 family of cytokines. The IL-1 beta cytokine is produced by activated macrophages as a proprotein, which is proteolytically processed to its active form by caspase 1 (CASP1/ICE). This cytokine is an important mediator of the inflammatory response, and is involved in a variety of cellular activities, including cell proliferation, differentiation, and apoptosis. Equine IL-1 beta Recombinant Protein is purified interleukin-1 beta cytokine produced in yeast.

Description: IL-1 alpha (IL-1α, IL-1F1) is a member of the interleukin 1 family of cytokines. IL-1 alpha is an inflammatory cytokine active in the initiation of the inflammatory reaction and in driving Th1 and Th17 inflammatory responses. Equine IL-1 alpha Recombinant Protein is purified interleukin-1 alpha cytokine produced in yeast.

Description: The IL-12 p40 subunit, or interleukin-12 beta subunit, is the 40 kD cytokine receptor-like subunit of the heterodimeric cytokines IL-12 and IL-23. IL-12 is involved in the differentiation of naive T cells into Th1 cells and the growth and function of T cells. Both IL-23 and IL-12 can activate the transcription activator STAT4 and stimulate the production of interferon-gamma (IFNG). Swine IL-12 p40 Recombinant Protein is purified interleukin-12 p40 produced in yeast.
