Description: Fibroblast growth factor 5 (FGF-5) is a secreted, heparin-binding member of the FGF subfamily. FGFs possess broad mitogenic and cell survival activities and are expressed during embryonic development. FGF-5 is expressed in the mesenchyme, skeletal muscles, central nervous systems, and hair follicles. FGF-5 promotes cell differentiation and proliferation by binding FGF receptor 1 and FGF receptor 2 (FGFR1 and FGFR2, respectively). FGF-5 plays an important regulatory role in skeletal muscle development. FGF-5 has also been identified in neurons of the limbic system, especially those of the olfactory bulb and pyramidal cells of the hippocampus (Haub and Goldfarb).

Description: Basic fibroblast growth factor (bFGF) is a prototypic member of the fibroblast growth factor family. 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). bFGF has the β-trefoil structure (Ponting and Russell), binds to the four FGF receptor (FGFR) family members, and activates JAK/STAT, PI3K, ERK1/2, and other receptor tyrosine kinase (RTK) signaling pathways. It supports the maintenance of undifferentiated human pluripotent stem cells (Xu <i>et al.</i>; Kang <i>et al.</i>), stimulates human pluripotent stem cells to form neural rosettes (Zhang <i>et al.</i>), and improves proliferation of human mesenchymal stem cells and enhances chondrogenic differentiation (Solchaga <i>et al.</i>). This version of bFGF is the full-length bFGF protein encoded by the human FGF2 gene consisting of 154 amino acid residues. This product is animal component-free.

Description: Chemokine ligand 19 (CCL19), also known as macrophage inflammatory protein-3 beta (MIP-3β), is a member of the CC chemokine family, which plays key roles in inflammatory responses, T cell activation, homeostasis, and development (Yan <i>et al.</i>). CCL19 is expressed in lymph nodes, thymus, and activated bone marrow stromal cells; it binds to C-C motif chemokine receptor 7 (CCR7) to induce migration of macrophages, T cells, and B cells (Gibejova <i>et al.</i>). Clinically, the expression of CCL19 is correlated to autoimmune diseases such as rheumatoid arthritis and cancer (Pickens <i>et al.</i>; Zhang <i>et al.</i>).

Description: Indian hedgehog (IHH) is one of three proteins in the hedgehog family which includes sonic hedgehog and desert hedgehog. Hedgehog proteins are important signaling molecules, acting through patched and smoothened receptors. During embryonic development, they are expressed in the fetal lung, gut, stomach, liver, kidney, and pancreas. IHH is strongly expressed in cartilage and regions of developing bone, and its signaling regulates growth and differentiation of bone tissue (Marigo <i>et al.</i>; Valentini <i>et al.</i>; St-Jacques <i>et al.</i>). IHH is also involved in yolk sac vasculogenesis, indicating a role in the differentiation of epiblast cells into endothelial and red blood cells (Byrd <i>et al.</i>). IHH induces the expression of parathyroid hormone-related peptide (PTHrP), which negatively regulates IHH during chondrocyte differentiation and proliferation (Vortkamp <i>et al.</i>).

Description: Stimulating T cells with JCV (LT) Peptide Pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. This peptide pool is a lyophilized mixture of 170 peptides from large T antigen (LT) of JC polyomavirus (JCV), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 688 on LT. LT is detectable during JCV latency (Rossi <i>et al.</i>), and in immunocompromised patients with JVC-associated pathologies such as progressive multifocal leukoencephalopathy (PML) (Delbue <i>et al.</i>). In PML, LT has been associated with activating the promoter of survivin, an anti-apoptotic protein (Del Valle <i>et al.</i>). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Description: SARS-CoV-2 Recombinant Spike Protein, aa319-541 is expressed in <i>Pichia pastoris</i> and is one of four structural proteins encoded by the SARS-CoV-2 genome. The Spike Protein plays a key role in attachment to host cells allowing invasion through clathrin-mediated endocytosis. The spike protein can be cleaved by host cell proteases after aa685 to yield the N-terminal S1 subunit, and C-terminal S2 region. The S1 subunit is responsible for interacting with the host cell receptor (angiotensin-converting enzyme II) through a receptor-binding domain that is highly conserved with SARS-CoV. The S1 subunit has two conformations: a ‘down’ conformation in which the receptor is inaccessible, and an ‘up’ conformation in which the receptor is accessible. These conformational changes are key for monoclonal antibody drugs and vaccine development. At the amino terminus of the polypeptide chain, SARS-CoV-2 Recombinant spike protein contains a polyhistidine tag and a SUMOstar site.

Description: Use autotaxin (ENPP2) to catalyze the production of lysophosphatidic acid (LPA), a potent mitogen that can evoke growth factor-like responses (Moolenaar and Corven), from lysophospholipids in extracellular fluids. Autotaxin is a secreted glycoprotein that belongs to the ectonucleotide pyrophosphatase/phosphodiesterase (ENPP) family, containing two N-terminal somatomedin B (SMB)-like domains, a central phosphodiesterase (PDE) domain with an active catalytic site, and a C-terminal nuclease-like (NUC) domain (Nishimasu <i>et al.</i>). Dysregulation of autotaxin and LPA receptors is implicated in cancer (Tigyi <i>et al.</i>), fibrosis (Ninou <i>et al.</i>), neurological disorders (Roy <i>et al.</i>), and other inflammation-associated conditions. Both Autotaxin and LPA are overexpressed in many cancers and can promote cell proliferation, migration, and resistance to apoptotic death (Tigyi <i>et al.</i>). Autotaxin was also found to catalyze the production of cyclic phosphatidic acid (CPA), an analog of LPA, which has anti-mitogenic and inhibitory effects on tumor cell invasion and metastasis (Fujiwara). This protein contains a His-residue tag at the amino end of the polypeptide chain. For consistency and reproducibility across your applications, Autotaxin from STEMCELL comes lyophilized with ≥ 85% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Description: Dickkopf-related protein 1 (DKK-1) is a member of the Dickkopf family and is a secreted protein that inhibits the canonical WNT pathway by competitive binding to low-density lipoprotein receptors (LRP)-5 and 6 with high affinity, thereby decreasing β-catenin protein stability (Niehrs). DKK-1 regulates embryonic development and contains two conserved cysteine-rich domains separated by a linker region and an N-terminal signal peptide (Krupnik <i>et al.</i>; Lieven <i>et al.</i>). A family of human DKK-related genes composed of DKK-1, DKK-2, DKK-3, and DKK-4 have been characterized together with a unique DKK-3 related protein termed Soggy (Krupnik <i>et al.</i>). DKK-1 has been shown to support the generation of myeloid-derived suppressor cells (MDSCs) and thus is a negative regulator of antitumor immune responses (D’Amico <i>et al.</i>). DKK-1 from thrombocytes is an important regulator of leukocyte infiltration and induces Th2 cell polarization and potentiates Th2 cell cytokine expression (Chae <i>et al.</i>). DKK-1 has also been shown to drive cardiac and retinal differentiation from induced pluripotent stem (iPS) cells (Lian <i>et al.</i>). Protein contains a His-residue tag at the carboxyl end of the polypeptide chain.
