Mouse Recombinant IL-10 (from E. coli)

Supplier: VWR International
Description: Interleukin 10 (IL-10) is an anti-inflammatory cytokine produced by macrophages and type 2 T helper (Th2) cells.  IL-10 inhibits the production of pro-inflammatory cytokines such as interferon gamma (IFN-ƴ), tumor necrosis factor alpha (TNF-α), interleukin 2 (IL-2), interleukin 3 (IL-3), interleukin 4 (IL-4), and granulocyte-macrophage colony-stimulating factor (GM-CSF), made by macrophages and regulatory T cells. IL-10 also suppresses antigen presentation on antigen presenting cells, and enhances the survival, proliferation, and antibody production of B cells.  Mouse IL-10 is not active on human cells.

Mouse Recombinant IL-21 (from E. coli)

Supplier: VWR International
Description: Interleukin 21 (IL-21) is a member of the common-gamma chain family of cytokines that are involved in immunoregulation. IL-21 is normally expressed by activated CD4+ T cells. The IL-21 receptor (IL-21R) activates the JAK/STAT signaling pathway and is expressed on T, B, and natural killer (NK) cells. Within the B cell lineage, IL-21 is a switch factor regulating IgG1 and IgG3 antibody production. IL-21 also cooperates with interleukin 4 (IL-4) for the production of multiple antibody classes in B cells. IL-21 has pleiotropic effects on the proliferation, differentiation, and effector functions of B, T, NK, and dendritic cells.

Rat 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-6 (from E. coli)

Supplier: VWR International
Description: Interleukin 6 (IL-6) is an important pro-inflammatory and anti-inflammatory cytokine expressed by T cells, macrophages, and muscle cells.  IL-6 signals through a receptor complex containing two receptors, IL-6Rα and gp130.  IL-6 has an important function in promoting fever and can serve to stimulate an immune response to trauma.  IL-6 is often used for growth of hybridoma cell lines.  Human IL-6 is active on mouse and rat cells.

Mouse Recombinant IFN-G (from E. coli)

Supplier: VWR International
Description: 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.

Human Recombinant R-SPONDIN-1 (from CHO cells)

Supplier: VWR International
Description: R-Spondin-1 (RSPO-1) is a secreted growth factor that stabilizes β-catenin and enhances WNT signaling. RSPO-1 is expressed in many tissues and regulates female sex determination, XX gonad development, oocyte differentiation, and hematopoietic stem cell specification. The RSPO-1 stabilization of β-catenin promotes intestinal crypt cell proliferation. This suggests that RSPO-1 functions as a stem cell growth factor and may have therapeutic potential in the treatment of gastrointestinal diseases and chemotherapy-induced intestinal mucositis. Additionally, recombinant RSPO-1 protein is used to initiate and maintain intestinal organoid cultures.

Human Recombinant OSM (from E. coli)

Supplier: VWR International
Description: Oncostatin M is a cytokine that is produced by macrophages, dendritic cells, and T lymphocytes during inflammatory events. The Type-I and Type-II Oncostatin M receptors are located on the cell surface of endothelial and tumor cells, contain the glycoprotein 130 (gp130) subunit, and activate the JAK/STAT signaling pathway.

Human Recombinant NAP-2 (from CHO cells)

Supplier: VWR International
Description: Neutrophil activating peptide 2 (NAP-2), also known as CXCL7, is a member of the CXC family of chemokines. NAP-2 is a carboxyl-terminal fragment produced by proteolytic cleavage of the platelet basic protein (PBP). NAP-2 is released from platelets and binds to the receptors CXCR1 and CXCR2 to chemoattract and activate neutrophils during inflammatory events.

Mouse Recombinant T REG CELL POLARIZING PB (from E. coli)

Catalog Number: (77753-610)
Supplier: VWR International
Description: Cytokines for polarizing T cells into T regulatory cells. T regulatory cells (Tregs) are a subset of T cells that suppress immune function. They are characterized by the expression of CD4, CD25 and Foxp3 and are known to produce immunosuppressive cytokines TGF-β 1 and IL-10. Tregs can be cultured from naive CD4+ T cells by culturing them in the presence of IL-2 and TGF-β 1 with CD3 and CD28 stimulation. In some cases cells are also cultured with neutralizing antibodies to IL-4, IFNγ and IL-12 and/or retinoic acid.
