{"product_id":"nsj-v3635-20ug","title":"Recombinant Napsin A Antibody \/ Rabbit Monoclonal, 20 ug","description":"\u003cp\u003eNapsin is a pepsin-like aspartic proteinase connected with maturation of surfactant protein B. There are two closely related napsins, napsin A and napsin B. Napsin A is expressed as a single chain protein. Immunohistochemical studies revealed high expression levels of napsin A in human lung and kidney but low expression in spleen. Napsin A is expressed in type II pneumocytes and in adenocarcinomas of lung. The high specificity expression of napsin A in adenocarcinomas of lung is useful to distinguish primary lung adenocarcinomas from adenocarcinomas of other organs.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":51548862873880,"sku":"V3635-20UG","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_b9853dfa-9739-41d1-9a5f-ad6351e30f4e.jpg?v=1768288119","url":"https:\/\/danabiosci.com\/products\/nsj-v3635-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
