Mouse Recombinant IL-6 (from E. coli)

Supplier: VWR International
Description: Interleukin 6 (IL-6) is a cytokine that is expressed by T cells, macrophages, and muscle cells. IL-6 acts to stimulate an immune response upon infection or trauma. IL-6 has both pro-inflammatory and anti-inflammatory functions, is capable of promoting fever, and signals through the cell-surface type I cytokine receptor complex containing the IL-6Ra and gp130 chains. Human IL-6 is active on mouse and rat cells.

Human Recombinant IL-4 (from E. coli)

Supplier: VWR International
Description: Interleukin 4 (IL-4) is an immunomodulatory cytokine that functions to induce naïve helper T cells to differentiate into type 2 T helper (Th2) cells. Th2 cells subsequently produce more IL-4 in a positive feedback loop. IL-4 also promotes immunoglobulin IgG to IgE isotype switching on B cells. IL-4 binds the IL-4Rα receptor to activate STAT6 signaling.

Human Recombinant SCF (from E. coli)

Supplier: VWR International
Description: Stem cell factor (SCF) is a cytokine made by fibroblasts and endothelial cells. SCF binds to the receptor c-Kit/CD117 and plays a critical role in the maintenance, survival, and differentiation of hematopoietic stem cells. While human SCF shows no activity on murine cells, murine and rat SCF are active on human cells.

Human Recombinant IL-8 (from E. coli cells)

Supplier: VWR International
Description: Interleukin 8 (IL-8 or CXCL8) is a member of the CXC cytokine family and is produced by macrophages, epithelial, smooth muscle, and endothelial cells. IL-8 binds the G protein-coupled serpentine receptors CXCR1 and CXCR2. IL-8 recruits innate immune cells, induces phagocytosis, and stimulates angiogenesis.

Human Recombinant EOTAXIN-3 (from E. coli)

Supplier: VWR International
Description: Eotaxin-3, also known as CCL26, MIP-4-alpha, and TSC-1, is a chemokine that is made by vascular endothelial and lung epithelial cells following interleukin 4 (IL-4) or interleukin 13 (IL-13) stimulation. Eotaxin-3 signals through the G protein-coupled chemokine receptor CCR3 to recruit eosinophils and basophils to inflammatory sites.

Mouse Recombinant MIP-1 A (from E. coli)

Supplier: VWR International
Description: Macrophage inflammatory protein-1 alpha (MIP-1 α), also known as CCL3, is a cytokine produced by macrophages. MIP-1 α binds the chemokine receptors CCR1, CCR4, and CCR5 to induce inflammatory responses, including the recruitment of granulocytes and neutrophil superoxide production. The MIP-1 α and MIP-1 β heterodimer exhibits antiviral activity against the human immunodeficiency virus 1 (HIV-1).

Human Recombinant IL-7 (from E. coli)

Supplier: VWR International
Description: <p>Interleukin 7 (IL-7) is a hematopoietic cytokine that is an important regulator of B and T cell development. IL-7 is secreted by bone marrow and thymic stromal cells, dendritic cells, intestinal epithelial cells, hepatocytes, and keratinocytes. IL-7 signals through the interleukin 7 receptor (IL-7R) to promote the differentiation of hematopoietic stem cells into T cells, B cells, and natural killer cells. IL-7 is also a regulator of intestinal mucosal lymphocyte proliferation. Human and mouse IL-7 show species cross-reactivity.</p>

Human Recombinant MCP-2 (from E. coli cells)

Supplier: VWR International
Description: Monocyte chemotactic protein 2 (MCP-2), also known as CCL8, is a cytokine that is important during allergic and inflammatory responses. MCP-2 activates mast cells, eosinophils, and basophils through the G protein-coupled chemokine receptors CCR1, CCR2B, and CCR5. MCP-2 signaling through the CCR5 receptor also functions as a natural inhibitor of the human immunodeficiency virus, type 1 (HIV-1).

Human Recombinant IFN-G (from E. coli)

Supplier: VWR International
Description: <p>Interferon gamma (IFN-γ) is a type II interferon that is critical during adaptive and innate immune responses to infection. IFN-γ is produced by T cells and natural killer cells following antigen-specific activation. IFN-γ binds IFN-γ receptors (IFN-γ R1 and IFN-γ R2), which are expressed on most immune cells, to activate the JAK-STAT pathway. IFN-γ-induced signaling increases the expression of class 1 major histocompatibility complex (MHC) molecules. Human IFN-γ is not cross-reactive with mouse IFN-γ.</p>

Human Recombinant IL-19 (from E. coli cells)

Supplier: VWR International
Description: Interleukin-19 (IL-19) is a member of the interleukin 10 (IL-10) cytokine family and is produced by B cells and monocytes. IL-19 binds the interleukin 20 receptor complex (IL-20R) to activate STAT3 signaling. IL-19 induces interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-a) expression in monocytes, and promotes T helper 2 (Th2) cell-mediated immune responses.
