Mouse/Rat Recombinant RANTES (CCL5)

Supplier: STEMCELL Technologies

RANTES (regulated upon activation, normal T cell expressed and secreted), also known as CCL5, is a member of the CC family of chemokines and is able to recruit leukocytes to sites of inflammation (Schall et al.). RANTES is secreted by T lymphocytes, macrophages, platelets, synovial fibroblasts, tubular epithelium, and certain types of tumor cells (Aldinucci and Colombatti; Soria and Ben-Baruch). This chemokine exerts its effect by interacting with the chemokine receptors CCR1, CCR3, CCR4, and CCR5. RANTES plays an active role in recruiting a variety of leukocytes into inflammatory sites, including T cells, macrophages, eosinophils, and basophils. In collaboration with certain cytokines that are released by T cells such as IL-2 and IFN-γ, RANTES also induces the activation and proliferation of NK cells to generate CC chemokine-activated killer cells, which are highly cytolytic (Lv et al.; Maghazachi et al.). It has been shown that RANTES produced by CD8+ T cells inhibits HIV infection of primary human peripheral blood mononuclear cells (Appay and Rowland-Jones; Cocchi et al.).

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.).

Human Recombinant IL-6, ACF

Supplier: STEMCELL Technologies

Interleukin 6 (IL-6) is a pleiotropic growth factor with the wide range of biological activities in immune regulation, hematopoiesis, and oncogenesis. IL-6 is produced by a variety of cell types including T cells, B cells, monocytes and macrophages, fibroblasts, hepatocytes, vascular endothelial cells, and various tumor cell lines. On its own or in combination with other factors such as IL-2 and interferon-γ, IL-6 stimulates the proliferation of B cells, T cells, and hybridoma cells (Hirano et al.; Mihara et al.; Tanaka et al). In combination with cytokines such as IL-3, GM-CSF and SCF, IL-6 has been shown to promote hematopoietic progenitor cell proliferation and differentiation in vitro. IL-6 signals through a cell surface type I cytokine receptor complex consisting of the ligand-binding IL-6α (CD126) and the signal-transducing gp130 subunits. The binding of IL-6 to its receptor system includes activation of JAK/STAT signaling pathway (Mihara et al.; Peters et al.; Tanaka et al.). This product is animal component-free.
