Description: Fibroblast growth factor 6 (FGF-6) is a heparin-binding member of the FGF family, regulators of cell proliferation, differentiation, and function. FGF-6 binds and signals through the FGF receptors 1c, 2c, and 4 (Ornitz <i>et al.</i>). FGF-6 is a potent mitogen for fibroblasts, vascular endothelial cells, and prostate carcinoma cells (Asada <i>et al.</i>; Pizette <i>et al.</i>; Ropiquet <i>et al.</i>). FGF-6 is primarily expressed in epithelial and mesenchymal cell lineages. During development, FGF-6 is expressed in skeletal muscle, consistent with its role in muscle differentiation and regeneration (Floss <i>et al.</i>). FGF-6 has also been shown to promote chondrogenesis in embryonic somites in conjunction with transforming growth factor beta 2 (TGF-β2; Grass <i>et al.</i>).

Description: Fibroblast growth factor 16 (FGF-16) is a heparin-binding member of the FGF family. FGFs possess broad mitogenic and cell survival activities and are expressed during embryonic development. FGFs act primarily on cells of mesodermal and neuroectodermal origin to regulate diverse physiological functions including angiogenesis, cell growth, pattern formation, embryonic development, metabolic regulation, cell migration, and tissue repair (Goldfarb; Green <i>et al.</i>). <i>in vitro</i>, FGF-16 has been shown to promote the proliferation of brown adipocytes and in rat embryos it is predominantly expressed in these cells. FGF-16 has also been shown to play a critical role in embryonic heart development and is thought to play a cardioprotective role after birth (Hotta <i>et al.</i>; Lu <i>et al.</i>; Wang <i>et al.</i>).

It is frequently used as a negative control. Actin, alpha skeletal muscle, is part of the highly conserved actin protein family and is the predominant isoform found in adult skeletal muscle (Laing <i>et al.</i>).

Description: 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 <i>et al.</i>). The chemokine domain is connected to an extended mucin-like stalk, followed by a transmembrane region, and a C-terminal intracellular domain (Imai <i>et al.</i>; Jones <i>et al.</i>). 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 <i>et al.</i>; 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).

Description: Trigger a variety of immunological responses with <i>E. coli</i> Lipopolysaccharide O55:B5 (S-form), a lipopolysaccharide (LPS) derived from the O55:B5 serotype of the Gram-negative bacteria and nbsp <i>Escherichia coli</i>. Composed of a lipid A, a core oligosaccharide, and an O antigen, LPS are glycolipid constituents that reside on the outer membranes of gram-negative bacteria (Kitchens RL <i>et al.</i>). LPS protects bacteria against bile salts and lipophilic antibiotics by maintaining the outer integrity of the cell membrane (Bäckhed F <i>et al.</i>). <i>E. coli</i> lipopolysaccharide O55:B5 (S-form), in particular, is predominantly recognized by toll-like receptor 4 (TLR4), which leads to the activation of NF-κβ, a protein complex which plays a key role in regulating immune response (Kuzmich N <i>et al.</i>). Activation of NF-κβ can trigger increased production of pro-inflammatory cytokines IL-1 and TNF-α by macrophages (Matuschak GM <i>et al.</i>). This LPS can also interact with CD14 to activate phospholipase Cγ2 and kinases of the Src family, trigger influxes of extracellular Ca2+, as well as calcineurin-dependent translocation of the nuclear factor of activated T cells (NFAT) family of transcription factors (Li CC <i>et al.</i>). When added to ImmunoCult™-SF macrophage medium (Catalog #10961), stimulation with lipopolysaccharide from <i>E. coli</i> (O55:B5) and IFN-γ supports the polarization to M1 (classically activated) macrophages.

Description: Use hepassocin to bind to lymphocyte-activation gene 3 (LAG-3) in an MHC class II independent manner, and inhibit antigen-specific T-cell activation (Wang <i>et al.</i>). Hepassocin is known to play a restorative role in the liver, reducing apoptosis and accelerating hepatocyte proliferation <i>in vivo</i> (Li <i>et al.</i>). In addition to these hepatoprotective effects, studies have shown that hepassocin expression is upregulated in gastric cancer tissues (Zhang <i>et al.</i>) and in breast cancer cells (Du <i>et al.</i>), suggesting it has potential to predict cancer disease progression. Hepassocin is a member of the fibrinogen superfamily, whose members share a fibrinogen domain at their C-terminus. It is predominantly expressed in the liver, and weakly in the pancreas (Hara <i>et al.</i>), and is secreted as a homodimer that consists of 312 amino acids. Hepassocin is an acute-phase reactant whose expression in HepG2 cells has been shown to be regulated by IL-6 (Liu and Ukomadu). This protein product contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, hepassocin from STEMCELL comes lyophilized with ≥ 87% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Description: Interferon-gamma (IFN-γ), also known as type II interferon, is produced by T and NK cells, and in smaller amounts by dendritic cells and macrophages. IFN-γ is controlled by cytokines such as IL-12 and IL-18 secreted in response to infection (Schroder <i>et al.</i>). IFN-γ binds to a receptor complex and initiates signal transduction via the JAK/STAT pathway; this culminates in the transcription and activation of many genes that control a diverse array of immunological functions (De Weerd and Nguyen; Krause <i>et al.</i>). IFN-γ stimulates the antimicrobial and anti-tumor activity of macrophages, NK cells, and neutrophils (Billiau and Matthys) by promoting the activation of microbial effector functions such as production of reactive oxygen species, NO intermediates, complement, etc. (Schroder <i>et al.</i>). IFN-γ enhances MHC class I and II expression in dendritic cells and mononuclear phagocytes, as well as the production of IL-12 by dendritic cells. In B cells, IFN-γ stimulates survival and growth in both mouse and human cells, and redirects B cells from proliferation towards differentiation. IFN-γ favors the development of Th1 vs Th2 cells and stimulates monocyte differentiation and function (Schroder <i>et al.</i>).

Description: Stimulating T cells with EBV (LMP2A) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. EBV (LMP2A) peptide pool is a lyophilized mixture of 27 peptides from latent membrane protein 2A (LMP2A) of Epstein-Barr virus (EBV; strain GD1), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 118 on LMP2A. LMP2A contributes to the survival of EBV-transformed B cells (Mancao and Hammerschmidt) and mediates partial escape of infected B cells from recognition by EBV-specific CD8+ T cells (Rancan et al). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.
