HHV6 (U54) Peptide Pool

HHV6 (U54) Peptide Pool

Supplier: STEMCELL Technologies

Stimulating T cells with HHV6 (U54) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HHV6 (U54) peptide pool is a lyophilised mixture of 112 peptides from protein U54 of human herpesvirus 6B (HHV-6B; strain Z29), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 459 on U54. U54 is a tegument transactivator and is suggested to be a homolog of the CMV UL82/83 (pp65/72K) protein (Isegawa et al.; Nicholas). In infected T cells, U54 has been shown to inhibit gene transcription of interleukin 2 (IL-2), the T cell growth factor, which likely contributes to viral persistence (Iampietro et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Mouse Recombinant Noggin

Mouse Recombinant Noggin

Supplier: STEMCELL Technologies

Noggin binds to and antagonizes bone morphogenetic protein (BMP) ligands of the transforming growth factor beta (TGF-β) family. Noggin supports maintenance of undifferentiated human embryonic stem cells cultured in mouse embryonic fibroblast (MEF)-conditioned medium (Chaturvedi et al.), and promotes dopaminergic differentiation of embryonic stem cells and subsequent survival of dopamine neurons (Chiba et al.). Noggin is essential for development of ectodermal structures including neural tube, tooth, hair follicle, and eye, as well as patterning of mesodermal somites and skeletal structures. It also influences chondrogenesis, osteogenesis, and joint formation (Krause et al.).

Human Recombinant C-Reactive Protein

Human Recombinant C-Reactive Protein

Supplier: STEMCELL Technologies

A member of the pentraxin family of proteins, C-reactive protein (CRP) plays important roles in host defenses, including regulating complement activation in vivo (Sjoberg et al.), decreasing nitric oxide production, and inhibiting angiogenesis in vitro (Verma et al., 2002). At specific concentrations, CRP directly inhibits endothelial progenitor cell (EPC) differentiation, survival, and function, and is thus implicated in the development of cardiovascular diseases (Verma et al., 2004). CRP is primarily synthesized by liver hepatocytes, but also by other immune cells, such as macrophages and lymphocytes (Sproston and Ashworth). The expression of this acute-phase protein is induced by IL-6 and IL-1 secretion of macrophages and T-cells during inflammation. For consistency and reproducibility across your applications, C-reactive protein from STEMCELL comes lyophilised with ≥87% purity, and endotoxin levels are verified to be ≤1,0 EU/μg protein.

CMV (IE1) Peptide Pool

CMV (IE1) Peptide Pool

Supplier: STEMCELL Technologies

Stimulating T cells with CMV (IE-1) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. CMV (IE-1) peptide pool is a lyophilised mixture of 120 peptides from the immediate early protein IE1 (IE1) of human cytomegalovirus (CMV; strain AD169), and consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 491 on IE1. CMV IE1 is a transcriptional transactivator and autoregulator (Cherrington and Mocarski). Studies show that IE1 promotes viral transcription by antagonizing histone deacetylation (Nevels et al.) and, along with IE2, may contribute to the survival of CMV-infected cells by blocking tumor necrosis factor alpha (TNF-α)-induced apoptosis (Zhu et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Human Recombinant BMP-4

Human Recombinant BMP-4

Supplier: STEMCELL Technologies

Bone morphogenetic protein 4 (BMP-4) is a member of the highly conserved transforming growth factor β (TGF-β) superfamily. Mature BMP-4 is a disulfide-linked homodimeric protein consisting of two 116-amino-acid residue subunits, and is generated by the proteolytic removal of the signal peptide and propeptides (Xiao et al.). BMP-4 binds to type I and type II receptors on cells. This binding results in the phosphorylation of receptor 1, which in turn results in the phosphorylation of Smad proteins, which then go on to act as transcription factors (Zhang et al.). BMPs have been shown to be key regulators of embryogenesis and are known to play a role in the growth and differentiation of various cell types, including embryonic stem (ES) cells, induced pluripotent stem (iPS) cells, mesenchymal cells, epithelial cells, hematopoietic cells, and neuronal cells (Chadwick et al.; Graham et al.; Jones et al.; Lengerke et al.; Zhang et al.).

HIV-1 (B Gag) Peptide Pool

HIV-1 (B Gag) Peptide Pool

Supplier: STEMCELL Technologies

Stimulating T cells with HIV-1 (B Gag) peptide pool releases downstream cytokines and upregulates activation markers, enabling antigen-specific T cells to be detected or isolated for analysis. HIV-1 (B Gag) Peptide Pool is a lyophilised mixture of 123 peptides from the gag polyprotein of human immunodeficiency virus 1 (HIV-1). The pool consists of 15-mer peptides with 11-amino-acid overlaps that cover amino acids 1 to 500 on gag polyprotein. The HIV-1 gag polyprotein is a key mediator of viral particle assembly (Campbell and Rein; Dong et al.), and together with the endosomal sorting complexes required for transport (ESCRT), results in budding during virion release (Carlson et al.). Viral peptide pools are useful for a broad range of applications, including vaccine development, immunological research, and diagnostic assay development.

Human Recombinant TGF-alpha

Human Recombinant TGF-alpha

Supplier: STEMCELL Technologies

Transforming growth factor-alpha (TGF-α) a member of the epidermal growth factor (EGF) family that is expressed in normal epithelial cells, monocytes, macrophages, brain cells, keratinocytes, and cancer cells. TGF-α binds EGF receptor (EGFR) and activates tyrosine kinase signaling. In epidermal and epithelial cells, this results in proliferation and differentiation. TGF-α is not structurally or genetically related to TGF-β, and the two ligands act through different signaling pathways. In vitro, TGF-α was shown to stimulate anchorage-independent growth (Singh and Coffey).

Mouse Recombinant IL-7

Mouse Recombinant IL-7

Supplier: STEMCELL Technologies

Interleukin 7 (IL-7) is a member of the type I cytokine family that is critical for T and B cell development and survival. It is produced by non-hematopoietic cells in the thymus, lymphoid organs, and by bone marrow stromal cells (Lundström et al.). IL-7 binds to a receptor composed of common gamma chain and IL-7Ra (CD127) and signals through the JAK/STAT and PI3K pathways. IL-7 regulates the survival of naïve and memory CD4+ and CD8+ T cells, γδ T cells, NK T cells, innate lymphoid cells, and T regulatory cells (Carrette and Surh), and provides signals to promote survival, proliferation, and differentiation during B cell development (Clark et al.; Corfe and Paige).

Human Recombinant IL-1 beta

Human Recombinant IL-1 beta

Supplier: STEMCELL Technologies

Interleukin 1 beta (IL-1β) is synthesized as an inactive precursor protein or pro-IL-1β. This precursor is cleaved intracellularly by caspase 1 (IL-1β convertase) to form the active form of the protein that is later secreted (Allan et al.). IL-1β binds to IL-1 receptor and activates intracellular signaling via the MAPK or NF-κB pathway. IL-1β is released by monocytes, tissue macrophages, and dendritic cells in response to infection or injury and induces expression of acute-phase proteins. It also promotes the infiltration of inflammatory and immunocompetent cells from the circulation into the extravascular space and affected tissues, by stimulating the expression of adhesion molecules on endothelial cells. IL-1β also affects other immune cells; for example, it co-stimulates T cell functions together with an antigen or mitogen. It also stimulates Th17 differentiation and B cell proliferation in an IL-6-dependent manner.
