Napsin A [clone EP205], anti-human

Description: Napsin A is an aspartic proteinase that belongs to the peptidase A1 family and plays a role in pneumocyte surfactant processing. In normal tissue, Anti-Napsin A specifically labels type II pneumocytes in adult lung and epithelial cells in kidney tissues. In abnormal tissues, Napsin A is strongly positive in over 80% of primary lung adenocarcinomas and 79% of renal cell carcinoma by immunohistochemistry. Napsin A is a useful marker for lung adenocarcinoma. The combined use of Napsin A and thyroid transcription factor (TTF) improves the sensitivity and specificity for identification of pulmonary adenocarcinoma Localization: cytoplasmDilution: 50-200Positive Control: lung caHIER: citrate pH6.0 or EDTA pH8.0Status: RUO
