Clone Host Grade Applications
Monoclonal Mouse Ascites IH
This monoclonal antibody is a general marker for neurohormonal peptide producing cells (APUD) and neoplasms derived from these cells. Utrastructural studies have shown that the antigen is located in the secretory granules and therefore poorly granulated endocrine cells stain weakly or not at all. This should be considered when using this antibody.
