Anti-Plexin-A1 (extracellular) Antibody (#APR-081) is a highly specific antibody directed against an epitope of the human protein. The antibody can be used in western blot and immunohistochemistry applications. The antibody recognizes an extracellular epitope and is thus ideal for detecting the protein in living cells. It has been designed to recognize PLXNA1 from mouse, rat and human samples.
