A single highly polymorphic gene locus PUM codes for a family of mucin-type glycoproteins present in human urine. These glycoproteins can be detected after electrophoresis using a group of monoclonal antibodies which show marked tumour specificity on immunohistology and include the HMFG and Ca antibodies (Swallow et al., 1986, 1987). Here we show by electrophoretic analysis of lung specimens and urine samples from nine individuals, that the PUM locus is expressed both in malignant and in normal lung. In contrast immunohistology of frozen sections of normal lung showed very little staining using the same antibodies, occasional reactive type 2 pneumocytes alone staining, whilst the carcinoma material showed strong staining in each case. However, after formalin fixation much more staining was observed in normal lung, all type 1 and 2 pneumocytes being stained. These observations suggest a difference in accessibility of the epitopes in normal and malignant lung, rather than a difference in expression of the PUM gene.
