Anti-PTN Antibody

This unconjugated rabbit polyclonal IgG primary antibody, supplied by Antibodies.com in a 200 µl vial, targets human and mouse pleiotrophin (PTN), a secreted 18 kDa heparin-binding growth factor involved in angiogenesis, neural development, and tumor progression. Validated for western blot and immunohistochemistry workflows, the reagent supports detection of endogenous PTN expression in cell lysates and fixed tissue sections from both species. Researchers apply this reagent to investigations of glioblastoma, breast carcinoma, and developmental neurobiology, where PTN levels are commonly used as indicators of proliferative and migratory signaling. The polyclonal format offers broader epitope coverage than monoclonal alternatives, which is useful when monitoring PTN expression changes across multiple tissue contexts. To maintain antibody activity, aliquot upon receipt and store according to the handling instructions included with the vial.
