Rat Recombinant M-CSF (from E. coli)

Supplier: VWR International
Description: Macrophage colony stimulating factor (M-CSF) is a hematopoietic growth factor that is widely produced by a variety of cells. M-CSF stimulates the proliferation and differentiation of hematopoietic stem cells into monocyte and macrophage cell types. M-CSF also acts through the colony stimulating factor 1 receptor (CSF1R) to modulate processes involved in immunology, bone metabolism, fertility, and pregnancy.

Mouse Recombinant IL-17A (from E. coli cells)

Supplier: VWR International
Description: Interleukin 17A (IL-17A), also known as CTLA-8, is a member of the IL-17 family of proteins. IL-17A is a proinflammatory cytokine that is secreted by activated CD4+ and CD8+ T lymphocytes. IL-17A acts through its receptor, IL-17R, to promote increased cytokine and chemokine secretion. In turn, the cytokines and chemokines mediate the immunoregulatory function of IL-17A by promoting the proliferation, maturation, and chemoattraction of neutrophils to inflammatory sites.

Mouse Recombinant Hematopoietic Stem Cell Expansion Protein Bundle (from E. coli)

Catalog Number: (77753-602)
Supplier: VWR International
Description: Cytokines for expansion and cell culture of mouse hematopoietic stem cells. Hematopoietic stem cells are self renewing pluripotent cells often characterized by the expression of CD34. Studies have shown that decreased expression of CD34 tends to correlate with decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of TPO, SCF, and FLT-3 Ligand for short time periods allows CD34+ cells to proliferate without decreasing CD34 expression, thus retaining their stem cell properties. The combination of these cytokines allows for the ex vivo expansion of the most immature hematopoietic stem cells in cord blood or bone marrow preparations, but can be supplemented with other cytokines to promote specific lineages.

Human Recombinant IL-34 (from CHO cells)

Supplier: VWR International
Description: Interleukin 34 (IL-34) was originally identified in humans, by large scale screening of secreted proteins; orthologs have also been found in chimpanzee, murine, rat and chicken. Human IL-34 is synthesized as a 242 amino acid (aa) precursor that contains a 20 aa signal sequence and a 222 aa mature chain. IL-34 is secreted as a homodimer and contains one potential N-glycosylation site.

Human Recombinant TH9 Cell Polarizing PB (from E. coli cells)

Catalog Number: (77753-620)
Supplier: VWR International
Description: Cytokines for polarizing human T cells into Th9 cells. Th9 cells are a unique subset of T helper cells that produce IL-9. An important function of IL-9 producing T cells is fighting inflammation and helminth infections. Th9 cells can be generated from naive CD4+ T cells in culture by culturing them in the presence of IL-4 and TGF-β 1. It also appears that IFNγ and IL-27 can inhibit the generation of Th9 cells.

Pig Recombinant IL-4 (from E. coli)

Supplier: VWR International
Description: Interleukin 4 (IL-4) is an immunomodulatory cytokine that functions to induce naïve helper T cells to differentiate into type 2 T helper (Th2) cells. Th2 cells subsequently produce more IL-4 in a positive feedback loop. IL-4 also promotes immunoglobulin IgG to IgE isotype switching on B cells. IL-4 binds the IL-4Rα receptor to activate STAT6 signaling.

Human Recombinant IL-31 (from E. coli)

Supplier: VWR International
Description: Interleukin 31 (IL-31) is an immunoregulatory cytokine that is expressed by activated type 2 T helper (Th2) cells. IL-31 signals through a heterodimer receptor consisting of the IL-31 Receptor A (IL-31RA) and the oncostatin M receptor (OSMR), which are expressed on monocytes, epithelial cells, and keratinocytes. IL-31 promotes allergic reactions and inflammatory skin diseases.

Human Recombinant BDNF (from E. coli)

Supplier: VWR International
Description: <p>Brain-derived neurotrophic factor (BDNF) is a nerve growth factor that binds two receptors, the low-affinity nerve growth factor receptor (LNGFR) and the tropomyosin receptor kinase B (TrkB), to support neuron growth and survival.  BDNF expression in the hippocampus is essential for long-term memory storage and learning.  Human, mouse, rat, and pig BDNF are cross-reactive.</p>

Mouse Recombinant VEGF-165 (from E. coli cells)

Supplier: VWR International
Description: Vascular endothelial growth factor A (VEGF-A) is produced by a wide variety of cell types, including tumor and vascular cells. VEGF-A is a mediator of vascular growth, vascular permeability, and plays a role in stimulating vasodilation via nitric oxide-dependent pathways. VEGF-A has several alternatively spliced isoforms, with VEGF-165 being the most abundant.

Pig Recombinant FLT-3 Ligand (from E. coli)

Supplier: VWR International
Description: Fms-related tyrosine kinase 3 ligand (FLT-3 ligand) is a growth factor that regulates hematopoietic cell proliferation. FLT-3 ligand signaling is transmitted through the fms-related tyrosine kinase 3 (FLT-3) receptor. FLT-3 ligand promotes the long-term expansion and differentiation of pro-B cells in the presence of interleukin 7 (IL-7) or in combination of IL-7 and interleukin 3 (IL-3).

Human Recombinant TARC (from E. coli)

Supplier: VWR International
Description: Thymus and activation regulated chemokine (TARC), also known as CCL17, is a chemokine that is constitutively produced by thymus tissue and activated peripheral blood mononuclear cells (PBMCs), including dendritic cells. TARC signals through the CCR4 receptor to induce chemotaxis of Type 2 T helper (Th2) cells. TARC is important in asthma and allergic diseases, along with bacterial and viral infections.

Human Recombinant M-CSF (from E. coli)

Supplier: VWR International
Description: Macrophage colony-stimulating factor (M-CSF) is a hematopoietic growth factor with broad production across different cell types (1). The regulation of monocyte and macrophage development to maintain homeostasis is primarily governed by M-CSF, which is generated by stromal cells present in both the bloodstream and tissues. Mature mononuclear phagocytes, in response, possess CSF-1 receptors (CSF-1R) and eliminate circulating CSF-1. This process creates a feedback mechanism responsible for diminishing monocyte proliferation (2, 3, 4). M-CSF also exerts its effects by interacting with CSF1R, influencing various processes related to immunology, bone health, fertility, and pregnancy regulation (5). Human M-CSF has cross reactivity to mouse cells, whereas mouse M-CSF does not exhibit activity on human cells (6).

Human Recombinant PDGF-AB (from E. coli)

Supplier: VWR International
Description: Platelet-derived growth factor (PDGF) is an important regulator of cell growth, proliferation, and angiogenesis. PDGF synthesis is induced by IL-1, IL-6, TNF-α, TGF-β and EGF signaling. PDGF functions as a mitogenic growth hormone on cells of mesenchymal lineage, such as smooth muscle and glial cells. PDGF is also stored in the alpha-granules of platelets and is released upon adherence to traumatized tissues.
