The hybridoma cell line (DSM ACC2002) produces a monoclonal antibody which detects the glycoprotein, having a molecular weight of about 52,000 Daltons, in human broncho-alveolar lavage samples. Moreover, the monoclonal antibody according to the invention has an immunhistochemical reaction with type II pneumocytes and Clara cells of the adult human lung tissue. In addition, the monoclonal antibody (SEC-41) detects human lung epithelial cells in the female foetus of the 18th week of pregnancy.de608615610620patent1991-4105374
