Human Recombinant LIF (from E. coli)

Supplier: VWR International
Description: Leukemia inhibitory factor (LIF) is a member of the interleukin 6 (IL-6) family that is made by a variety of adult and embryonic tissues. LIF signals through the glycoprotein 130 (gp130)/LIF receptor (LIFR) heterodimer to activate STAT3 and MAPK signaling. LIF functions during hematopoietic differentiation, neuronal cell differentiation, kidney development, and inflammatory processes. Human LIF may also be an important factor during human embryonic stem cell (hESC) self-renewal, pluripotency, and embryonic implantation.

Human/Mouse/Rat Recombinant Activin-A (from E. coli)

Supplier: VWR International
Description: Activin A is a member of the transforming growth factor beta (TGF-β) family of proteins and functions to stimulate follicle-stimulating hormone (FSH) secretion.  Activins are produced in many tissue types including the skin, gonads, lungs, and pituitary gland. Activins interact with receptor type I and type II serine/threonine protein kinases, to activate SMAD signaling and regulate diverse cellular functions, such as cell proliferation, differentiation, wound healing, apoptosis, and metabolism.  Activin A is a homodimer comprised of two activin βA chains. Cleavage of the N-terminal propeptide renders the Activin protein biologically active. Human Activin A shares 100% amino acid sequence identity with mouse, rat, porcine, bovine, and feline Activin A proteins.

Horse Recombinant PDGF-BB (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. PDGF is a dimeric glycoprotein formed by two A chains (AA), two B chains (BB), or as a heterodimer with an A and a B chain (AB). The PDGF dimer binds the cell surface receptor tyrosine kinases PDGFR-α and PDGFR-β.

Human Recombinant EBI3 (from E. coli)

Supplier: VWR International
Description: Epstein-Barr virus induced gene-3 (EBI3) is a secreted glycoprotein belonging to the hematopoietin receptor family related to the p40 subunit of interleukin 12 (IL-12). EBI3 expression is induced in B-lymphocytes in response to Epstein-Barr virus infection. EBI3 forms heterodimers with p28 to form interleukin 27 (IL-27), and with p35 to form interleukin 35 (IL-35). Both IL-27 and IL-35 have anti-inflammatory and regulatory activity.

Human Recombinant EG-VEGF (from E. coli)

Supplier: VWR International
Description: <p>Endocrine gland-derived vascular endothelial growth factor (EG-VEGF) is an angiogenic growth factor that is expressed in the ovaries, testis, adrenal, and placental tissues. EG-VEGF has mitogenic, chemoattractive, and antiapoptotic functional roles. EG-VEGF signaling is mediated through binding the G protein-coupled receptors prokineticin receptor 1 (PKR1) and prokineticin receptor 2 (PKR2). Polycystic ovaries display strong EG-VEGF expression that is associated with increased angiogenesis and cyst formation, which could lead to the formation of polycystic ovary syndrome and infertility.</p>

HB-EGF is the predominant growth factor involved in epithelialization during wound healing. HB-EGF signals through the receptor tyrosine kinase ErbB2 to maintain adult heart homeostasis, and promotes cardiac valve development through binding in high affinity to the epidermal growth factor receptor (EGFR). HB-EGF binds the the ErbB4 receptor tyrosine kinase to mediate implantation of the human blastocyst. HB-EGF also functions as a potent mitogen for fibroblasts and smooth muscle cells.

Human Hematopoietic Progenitor Cell Expansion Recombinant Protein Bundle

Catalog Number: (77753-604)
Supplier: VWR International
Description: Cytokines for expansion and cell culture of human hematopoietic stem cells to progenitor 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 the decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of SCF, FLT-3 Ligand, IL-6 and IL-3 for short time periods allows rapid expansion of immature and more mature hematopoietic progenitor cells in cord blood or bone marrow preparations.
