CD13 also known as alanyl aminopeptidase (AAP) and gp150. The clone WM15, a mouse monoclonal antibody recognizes a 150 kD type II integral membrane protein. It widely expressed in all cells of the myeloid lineage, activated endothelial cells, hematopoietic progenitor, and stem cells and not on platelets or erythrocytes. The latter enzyme was thought to be involved in the metabolism of regulatory peptides by diverse cell types. AAP is also used by some viruses as a receptor to which these viruses bind to and then enter cells.
We recommend that every lab carries out an initial titration study before running your samples to ensure that the optimal concentration is selected for your application.
