R&D Activin - Recombinant  Activin A Protein from Human/Mouse/Rat Activins and inhibins, members of the TGF-β superfamily, have been shown to have a wide range of biological activities including: mesoderm induction, neural cell differentiation, bone remodeling, hematopoiesis and reproductive physiology. Specifications and Use for R&D Activin ASource of R&D Activin• A DNA sequence encoding the human Activin A protein sequenc…

R&D Systems Recombinant Human IL-4 Interleukin-4 (IL-4), also known as B cell-stimulatory factor-1, is a monomeric, approximately 13 kDa - 18 kDa Th2 cytokine that shows pleiotropic effects during immune responses. It is a glycosylated polypeptide that contains three intrachain disulfide bridges and adopts a bundled four α-helix structure. Specifications and Use of R&D Systems Recombinant Human IL-4Source • A DNA sequence en…

R&D PDGF BB, CF - Recombinant PDGF-BB Human Protein Platelet-derived growth factor (PDGF) was discovered as a major mitogenic factor present in serum but absent from plasma. It was found to be secreted from the α-granules of platelets activated during the coagulation of blood to form serum. Specifications and Use of R&D PDGFSource of of R&D PDGF • A DNA sequence encoding the 109 amino acid residue mature human PDGF-B chain p…

TGF- β1 (transforming growth factor beta 1) is one of three closely related mammalian members of the large TGF-β superfamily that share a characteristic cystine knot structure.1 - 7 TGF-β1, -2 and -3 are highly pleiotropic cytokines that are proposed to act as cellular switches that regulate processes such as immune function, proliferation and epithelial-mesenchymal transition. Specifications and Use for R&D TGF-beta1Source •…
