Pleiotrophin (PTN) is a heparin-binding growth factor, also known as heparin-binding growth-associated molecule, heparin affin regulatory peptide, heparin-binding growth factor-8, heparin-binding neurotrophic factor and osteoblast-specific factor. PTN expression is found during development in cells that are in early differentiation stage. The biological functions of PTN include cell migration, proliferation, angiogenesis and differentiation of neural progenitor cells growth of neuritis and fetal lung development. Cellular signalling of PTN is mediated by the receptor protein tyrosine phosphatase (RPTP) β/zeta and is important in tumor growth, angiogenesis and metastasis. Over expression of PTN is observed in neurodegenerative disorders, breast, prostate, lung cancers, glioblastoma, meningioma and melanoma Anti-Pleiotrophin specifically recognizes human pleiotrophin.
Immunogen
purified recombinant human pleiotrophin expressed in Sf 21 cells.
Application
Anti-Pleiotrophin antibody may be used for immunoblotting at a working concentration of 0.1-0.2 μg/ml. The antibody was used for ELISA at a working antibody dilution of 1:200 using cutaneous nerve protein extracts of female Lewis rats.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose.

Schwann cell phenotype is classified as either myelinating or nonmyelinating. Additional phenotypic specialization is suggested, however, by the preferential reinnervation of muscle pathways by motoneurons. To explore potential differences in growth factor expression between sensory and motor nerve, grafts of
Mammalian lung development is a complex biological process, which is temporally and spatially regulated by growth factors, hormones, and extracellular matrix proteins. Abnormal changes of these molecules often lead to impaired lung development, and thus pulmonary diseases. Epithelial-mesenchymal interactions are
Pleiotrophin (PTN, Ptn) is a widely expressed, developmentally regulated 136 amino acid secreted heparin-binding cytokine. It signals through a unique signaling pathway; the PTN receptor is the transmembrane receptor protein tyrosine phosphatase (RPTP)beta/zeta. RPTPbeta/zeta is inactivated by PTN, which leads
