Human Recombinant Complement Factor D, His Tag

Human Recombinant Complement Factor D, His Tag

Supplier: STEMCELL Technologies

Complement factor D is a component of the alternative pathway of the complement system and part of the innate immune system, playing a vital role in the initiation and amplification of complement activation, in order to defend against infection (Barratt and Weitz). A serine protease belonging to the S1 peptidase family, complement factor D is secreted by adipocytes into circulating blood, and is also expressed by macrophages and monocytes (White et al.). In the initiation phase of the complement pathway, complement factor D cleaves complement factor B (bound to component C3) to produce a complex known as C3 convertase. During the amplification phase, complement factor D cleaves complement factor B (bound to component C3b) to produce the C3bBb convertase, and is involved in the propagation of complement activation. In addition to its immunological role, complement factor D is involved in other physiological processes, such as the efficient clearing of damaged cell debris by phagocytes following acute liver injury (Cresci et al.). Complement factor D deficiency is associated with an increased susceptibility to pathogens like Neisseria meningitidis (Biesma et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, complement factor D from STEMCELL comes lyophilised with ≥94% purity, and is verified by LAL analysis to ensure endotoxin levels are ≤1,0 EU/μg protein.

Human Recombinant Galectin-1

Human Recombinant Galectin-1

Supplier: STEMCELL Technologies

Galectin-1 (Gal1) was the first characterized member of the galectin family of galactosidase-binding proteins, with over 15 mammalian galectins identified (Camby et al.; Salatino et al.). Gal1 comes in two forms: the oxidized monomer that acts as a cytokine, and the reduced dimer that acts as a lectin (Gaudet et al.). This product is in the dimer form. This cytokine is expressed in many tissues and has an immunosuppressive role in affecting T cell homeostasis by various mechanisms such as regulating apoptosis, cytokine secretion, cell adhesion, cell proliferation, and other effects (Camby et al.; Garín et al.; Gaudet et al.; Salatino et al.). In addition, Gal1 is thought to also play a role in axonal regeneration after injuries (Camby et al.; Garín et al.; Gaudet et al.; Salatino et al.). There are several therapeutic applications suggested for Gal1; overexpression has been suggested as a therapy for autoimmune and inflammatory diseases and enhancing axonal regeneration in injured nerves (Camby et al.; Gaudet et al.). In contrast, inhibition of Gal1 has been suggested to prevent tumor metastasis and cancer progression, as it may aid in cell adhesion, migration, and immune escape of cancer cells (Camby et al.).

Human Recombinant GM-CSF (E. coli-expressed)

Human Recombinant GM-CSF (E. coli-expressed)

Supplier: STEMCELL Technologies

Granulocyte-macrophage colony-stimulating factor (GM-CSF) promotes the proliferation and differentiation of hematopoietic progenitor cells and the generation of neutrophils, eosinophils, and macrophages. In synergy with other cytokines such as stem cell factor, IL-3, erythropoietin, and thrombopoietin, it also stimulates erythroid and megakaryocyte progenitor cells (Barreda et al.). GM-CSF is produced by multiple cell types, including stromal cells, Paneth cells, macrophages, dendritic cells (DCs), endothelial cells, smooth muscle cells, fibroblasts, chondrocytes, and Th1 and Th17 T cells (Francisco-Cruz et al.). The receptor for GM-CSF (GM-CSFR) is composed of two subunits: the cytokine-specific α subunit (GMRα; CD116) and the common subunit βc (CD131) shared with IL-3 and IL-5 receptors (Broughton et al.). GM-CSFR is expressed on hematopoietic cells, including progenitor cells and immune cells, as well as non-hematopoietic cells. Recombinant human GM-CSF (rhGM-CSF) promotes the production of myeloid cells of the granulocytic (neutrophils, eosinophils and basophils) and monocytic lineages in vivo. It has been tested for mobilization of hematopoietic progenitor cells and for treating chemotherapy-induced neutropenia in patients. GM-CSF is able to stimulate the development of DCs that ingest, process, and present antigens to the immune system (Francisco-Cruz et al.).

Mouse Recombinant MIP-1 beta (CCL4)

Mouse Recombinant MIP-1 beta (CCL4)

Supplier: STEMCELL Technologies

Macrophage inflammatory protein-1 beta (MIP-1 beta), also known as CCL4, is a member of the CC family of chemokines and is most closely related to CCL3 (MIP-1 alpha). Cellular sources of MIP-1 beta include activated leukocytes (monocytes and T and B cells), brain endothelial cells, and smooth muscle cells (Lukacs et al.; Menten et al.). MIP-1 beta, MIP-1 alpha, and RANTES have been shown to be major HIV-suppressive factors, possibly through the interactions of these chemokines with the receptor CCR5 on CD4+ T cells, which is also a major receptor for HIV entry into CD4+ T cells (Cocchi et al.; Menten et al.). MIP-1 beta attracts a variety of immune cells to sites of microbial infection. In addition to its chemotactic functions, MIP-1 beta induces the release of proinflammatory cytokines, mast cell degranulation, and NK cell activation (Schall et al.). In mice, recruitment of regulatory T cells to B cells and antigen-presenting cells by MIP-1 beta plays a central role in the initiation of T cell and humoral responses, and the depletion of regulatory T cells or MIP-1 beta results in deregulated humoral responses and production of autoantibodies (Bystry et al.).

Human Recombinant M-CSF, ACF

Human Recombinant M-CSF, ACF

Supplier: STEMCELL Technologies

Macrophage colony-stimulating factor (M-CSF) is a homodimeric glycoprotein growth factor that regulates proliferation and differentiation of myeloid hematopoietic progenitors to mononuclear phagocytic cell lineages, including monocytes, macrophages, and osteoclasts. M-CSF is a crucial factor for the development of tissue-resident macrophages in most tissues (Ginhoux andamp; Jung). It is required for the maturation and activation of monocytes and macrophages, and regulates inflammatory responses in conjunction with other stimuli such as IFN-γ, LPS, and IL-4 (Murray et al.). M-CSF is also required for bone resorption by osteoclasts, and is involved in the development and regulation of placenta, mammary gland, and brain. M-CSF is produced by monocytes, fibroblasts, osteoclasts, stromal cells, endothelial cells, and tumor cells (Chockalingam andamp; Ghosh). M-CSF exerts its biological effects by signaling through a receptor tyrosine kinase (CSF-1R or M-CSF-R) encoded by the c-fms proto-oncogene (Hamilton). CSF-1R shares similar structural features with other growth factor receptors, including the stem cell factor (SCF) receptor, platelet-derived growth factor receptor (PDGF-R), and Flt3/Flk-2 receptor tyrosine kinase. Stimulation of the CSF-1R upon binding to M-CSF activates MAPK, PI3K, and PLCγ signaling pathways (Chockalingam andamp; Ghosh). Human and mouse M-CSF sequences are highly conserved both at nucleotide and amino acid levels (80% homology; DeLamarter et al.). This product is animal component-free.

Human Recombinant Midkine

Human Recombinant Midkine

Supplier: STEMCELL Technologies

Midkine is a member of a unique family of heparin-binding growth factors that are structurally different from other fibroblast growth factors (Muramatsu; Takada et al.). Midkine is a proinflammatory cytokine, promoting the migration of leukocytes, fibrinolysis, and acting as a chemotactic agent towards neutrophils (Muramatsu; Said et al.; Takada et al.). It also regulates growth, differentiation, and development during the midgestion stage of embryogenesis, and promotes angiogenesis (Muramatsu; Said et al.; Takada et al.). The protein structure consists of three antiparallel β-sheets and is highly conserved between species (Muramatsu; Takada et al.). While the exact signal pathway is not known, proposed pathways include promoting LRP, inhibiting Src kinase, activating paxillin and STAT1α, activating PI2 and MAP kinases, suppressing caspases, binding to α6β1-integrin and tetraspanin, activating FAK, phosphorylating STAT3, suppressing STAT5 phosphorylation, activating ALK, activating PI3 kinase and transcription of NFkB, binding to neuroglycan C or nucleolin, and binding to eIF3 (Muramatsu). In cultured cells, midkine influences growth and survival of neural precursor cells, synthesis of cytokines from endothelial and renal epithelial cells, and promotes synthesis of extracellular matrices from fibroblasts (Muramatsu; Takada et al.).

Human Recombinant CD200, His Tag

Human Recombinant CD200, His Tag

Supplier: STEMCELL Technologies

A type 1 membrane glycoprotein belonging to the immunoglobulin superfamily, cluster of differentiation 200 (CD200) binds the CD200 receptor (CD200R) that is expressed on the surface of myeloid cells and T cells (Wright et al.), and has been shown to inhibit myeloid cell activity and macrophage cytokine production (Jenmalm et al.). Homologues of CD200 have been identified in viruses and can interact with CD200R to reduce macrophage pro-inflammatory cytokine production (Foster-Cuevas et al.). Studies have shown that the immunosuppressive effects of CD200 can promote acceptance of allogeneic tissue grafts in hosts (Gorczynski et al.), whereas dysregulation of CD200/CD200R can contribute to the development of autoimmune conditions, such as rheumatoid arthritis (Ren et al.). CD200 contains two immunoglobulin-like domains, a V-type domain and a smaller C2-type domain (Hatherley et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, cluster of differentiation 200 from STEMCELL comes lyophilised with ≥95% purity, and is verified by LAL analysis to ensure endotoxin levels are ≤1,0 EU/μg protein. Human recombinant CD200 at 2 μg/ml can bind human CD200R (His and hFc tag) with a linear range of 5 to 28 ng/ml, as determined by functional ELISA.

Human Recombinant IL-11

Human Recombinant IL-11

Supplier: STEMCELL Technologies

Interleukin 11 (IL-11) is a pleiotropic cytokine with effects on various tissues including the bone marrow, brain, and intestinal mucosa (Du andamp; Williams). It belongs to the IL-6 family of cytokines that share a common signal transducer, gp130. IL-11 induces the proliferation of hematopoietic stem cells (Lemoli et al.) and megakaryocytic progenitor cells (Bruno et al.), the maturation of megakaryocytes (Burstein et al.), and the production of platelets (Neben et al.). IL-11 is produced by a variety of cell types including hematopoietic cells, mesenchymal cells, epithelial cells, and neuronal cells. It was first cloned from a cDNA library of the human bone marrow-derived stromal cell line KM-102 (Kawashima et al.). The binding of IL-11 to its receptor induces heterodimerization with the gp130 subunit and activation of JAK tyrosine kinases. IL-11 was the first pharmacologic agent approved for the treatment of chemotherapy-induced thrombocytopenia. IL-11 also plays a role in cancer progression by inducing the proliferation of epithelial cancer cells and the survival of metastatic cells at distant organs. Recently, IL-11 has gained interest for its role in the pathogenesis of diseases in dysregulated mucosal homeostasis associated with STAT3 upregulation, including gastrointestinal cancers (Putoczki et al.).

Mouse Recombinant IFN beta

Mouse Recombinant IFN beta

Supplier: STEMCELL Technologies

A cytokine belonging to the type 1 interferon family, Interferon beta (IFN beta) binds IFN alpha/beta receptors (IFNAR) that activate tyrosine kinases and initiate the interferon-induced Jak-STAT signaling pathway, which modulates many key immune processes (Smieja et al.). In an experimental model involving cardiac fibroblasts isolated from rats, IFN beta was found to induce both pro- and anti-inflammatory cytokines production by activating different STAT proteins (Bolivar et al.). The anti-inflammatory effects of IFN beta have been studied in the context of autoimmune disorders, and there are currently multiple approved IFN beta drugs for treatment of relapsing forms of multiple sclerosis (Filipi and Jack). IFN beta is produced by immune cells, including macrophages, and non-immune cells, such as fibroblasts and epithelial cells (Ivashkiv and Donalin). The crystal structure of IFN beta shares characteristics with other type I interferons. It comprises five alpha-helices with four of them forming a helix bundle, and one long and three shorter loops connecting the helices (Karpusas et al.). For consistency and reproducibility across your applications, interferon alpha 1 from STEMCELL comes lyophilised with ≥87% purity, specific activity EC50 ≤18 pg/mL, and LAL analysis verification ensuring endotoxin levels are ≤1,0 EU/μg protein.
