Lupeol ≥98%, crystals

Supplier: Cayman Chemical

Lupeol, a dietary triterpene found in certain fruits, vegetables, and medicinal plants, has potent anti-inflammatory, anticarcinogenic, antimutagenic, and antimalarial activity. It suppresses the growth of hepatocellular carcinoma cell lines SMMC7721 and HepG2 with IC50 values of 45 and 48.5 μM and melanoma cell lines Mel 928 and Mel 1241 with IC50 values of 75 and 72 μM.¹'² At 0.76 g/kg lupeol causes a significant decrease in the blood pressure of stroke-prone hypertensive rats and reduces expression of hepatic genes involved in triglyceride and cholesterol synthesis.³ It also has significant anti-inflammatory effects at 50 mg/kg in a carrageenan-induced edema model, inhibiting neutrophil migration.⁴

Human Recombinant GRO-beta (CXCL2)

Human Recombinant GRO-beta (CXCL2)

Supplier: STEMCELL Technologies

GRO (growth-regulated oncogene)-beta or CXCL2 is a member of the CXC family, which plays an integral role in recruitment and activation of neutrophils and basophils in response to tissue injury and microbial infection. GRO-beta and GRO-gamma are closely related to GRO-alpha and share 90% and 86% amino acid sequence homology, respectively, with GRO-alpha. Receptor-binding studies have demonstrated that GRO-alpha, -beta, and -gamma signal mainly through G protein-coupled receptors CXCR1 and CXCR2 (Ahuja and Murphy). GRO-beta is expressed in epithelial cells, monocytes, fibroblasts, and melanocytes and is further induced during inflammatory, epithelialization, and angiogenic processes, for example during the wound healing process of human burn wounds (Zaja-Milatovic and Richmond). GRO-beta also stimulates mitogenesis in certain human melanoma cells (Unemori et al.).

Human Recombinant IFN-beta (HEK293-expressed)

Human Recombinant IFN-beta (HEK293-expressed)

Supplier: STEMCELL Technologies

Use Interferon beta (IFN-β) to modulate the activity of genes that control dendritic cell activation, T cell survival, NK cell activation, chemokine expression, lymph node retention, and antiproliferative and antiviral effects (Dunn et al. Nat Rev Immunol, 2006). IFN-β binds to a receptor complex composed of IFNAR1 and IFNAR2, and initiates signal transduction via the JAK/STAT pathway. It is predominantly produced by fibroblasts, with smaller amounts from plasmocytoid dendritic cells. Macrophages and endothelial cells secrete IFN-β in response to viral infection (Reder and Feng. Front Immunol, 2013). IFN-β suppresses Th17 cells by affecting expression of IL-4, IL-10, and IL-27, and is a first-line treatment for multiple sclerosis. IFN-β was also shown to expand regulatory T cells and limit T cell trafficking to the central nervous system (Inoue and Shinohara. Immunology, 2013). Of the two IFN-β variants (IFN-β1 and IFN-β3), this product is the IFN-β1 form.

Human Recombinant Fractalkine (CX3CL1)

Human Recombinant Fractalkine (CX3CL1)

Supplier: STEMCELL Technologies

Fractalkine (CX3CL1) is a unique chemokine belonging to the CX3C family, and is characterized by a C-X3-C cysteine motif within the chemokine domain, near the amino terminus of the protein (Bazan et al.). The chemokine domain is connected to an extended mucin-like stalk, followed by a transmembrane region, and a C-terminal intracellular domain (Imai et al.; Jones et al.). The protein signals through interaction with a single receptor, CX3CR1, expressed on monocytes, natural killer cells, T cells, microglia, and smooth muscle cells. Fractalkine is upregulated in endothelial cells by inflammatory signals and is synthesized as a membrane-bound molecule that mediates cell migration and adhesion (White and Greaves). Cleavage at the base of the stalk by metalloproteinases generates a soluble chemokine, which functions as a potent chemoattractant of target cells (Garton et al.; Apostolakis and Spandidos). Fractalkine has been implicated in pathology of inflammatory diseases, such as atherosclerosis and other vascular diseases, and has anti-apoptotic functions (White and Greaves).

Human Recombinant IL-31

Human Recombinant IL-31

Supplier: STEMCELL Technologies

Interleukin 31 (IL-31), a four-helix bundle inflammatory cytokine, belongs to the IL-6 cytokine family which includes IL-6, oncostatin M, leukemia inhibitory factor (LIF), and cardiotrophin-1 ( Dillon et al.). IL-31 signals through a heterodimer composed of IL-31RA (also known as gp130-like receptor or GPL) and the oncostatin-M receptor (OSMR), both of which are expressed on monocytes (Diveu et al.; Ghilardi et al.), epithelial cells (Ip et al.), and keratinocytes (Kato et al.). Signaling through the GPL/OSMR complex activates the JAK/STAT, RAS/ERK, and PI3K/AKT signaling pathways, resulting in the downstream activation of STAT1, STAT3, and STAT5 transcription factors (Cornelissen et al.; Dambacher et al.; Dillon et al.; Ip et al.). IL-31 responses have been associated with allergic responses and inflammatory skin diseases including atopic dermatitis (Cornelissen et al.; Gangemi et al.).

Human/Mouse Recombinant FGF-8B, ACF

Human/Mouse Recombinant FGF-8B, ACF

Supplier: STEMCELL Technologies

Fibroblast growth factor 8B (FGF-8B) is a member of the fibroblast growth factor (FGF) family and is an isoform of FGF-8. Cytokines in the FGF family possess broad mitogenic and cell survival activities (Folkman and Klagsbrun; Kimelman and Kirschner) and are involved in a variety of biological processes, including cell proliferation, differentiation, survival, and apoptosis (Folkman and Klagsbrun; Klagsbrun; Rifkin and Moscatelli). FGF-8B signals through FGF receptors (FGFRs) to activate PI3K and MAPK pathways. FGF-8B regulates gastrulation, epithelial-mesenchymal transition, and mesenchymal to epithelial differentiation during embryonic development. FGF-8B has also been found in peripheral blood leukocytes and healthy bone marrow samples (Mattila and Härkönen). FGF-8B has mitogenic effects on somatic cells in the germinal epithelium and is expressed in adult mouse ovarian cells and tissues, which suggests that it regulates maturation of oocytes and seminiferous epithelium in testes (Valve et al.). This product is animal component-free.
