Immunohistochemical localization of thymopoietin with an antiserum to synthetic Cys-thymopoietin28-39.
Thymopoietin-containing cells in the thymus were identified immunohistochemically using murine antiserum generated by immunization with synthetic Cys-thymopoietin28-39 (Cys-TP28-39). human thymopoietin, This antiserum, previously shown to react with both bovine and human thymopoietin, gave reactivity restricted to cortical and medullary epithelial cells of bovine and human thymus. Monoclonal antibodies with reactivity restricted to native bovine thymopoietin did not react with tissue sections of bovine thymus; most likely the epitopes recognized by monoclonal antibodies are not expressed on the inactive precursor forms of thymopoietin within thymic epithelial cells.
