Anti-PTN Antibody

This rabbit polyclonal antibody targets human pleiotrophin (PTN), a secreted 18 kDa heparin-binding growth factor implicated in neural development, bone formation, and tumor angiogenesis. Supplied by Antibodies.com as a 50 µl vial of unconjugated IgG, the reagent is validated for Western blot (WB) and immunohistochemistry (IHC) on human and mouse samples. PTN expression is frequently examined in glioblastoma, breast carcinoma, and neuroblastoma research, where the antibody is used to track the secreted cytokine in conditioned media, tissue sections, and cell lysates. The polyclonal format delivers multi-epitope recognition of the mature pleiotrophin polypeptide, supporting detection across a range of experimental preparations. For short-term use, store aliquots refrigerated at 4°C; for longer-term storage, freeze at -20°C and limit freeze-thaw cycles to preserve activity. Researchers investigating midkine-PTN signaling, neural stem cell differentiation, or cancer microenvironment studies will find this reagent compatible with those workflows.
