Profile: Reprokine Ltd. focuses on development, manufacturing and marketing of immune reagents, E.coli and mammalian derived recombinant cytokines, growth factors, and labeled antibody products. We deal with recombinant cytokines & growth factors, recombinant antigens, cell culture reagents, conjugated antibodies, monoclonal antibodies, cytokine assay services and technology licensing. Platelet-derived growth factors (PGDF) are a set of the numerous growth factors that regulate cell growth and division. PDGFs play a role in embryonic development, cell proliferation, cell migration, and angiogenesis, and have also been linked to several diseases such as atherosclerosis, fibrosis and malignant diseases. Chemokines are a family of pro-inflammatory activation-inducible cytokines. These proteins are mainly chemotactic for different cell types. All chemokines possess a number of conserved cysteine residues involved in intramolecular disulfide bond formation, which allows chemokines to be grouped into families according to the presence or absence of one or more conserved cysteine residues.
