— A monoclonal antibody, RL23/36, reacting preferentially with a determinant expressed on normal human hepatocytes is described. Use of an immunohistochemical technique on frozen sections from a range of 75 human liver biopsy specimens revealed that the determinant detected by RL23/36 was not expressed on hepatocytes from a number of patients with biopsy‐proven liver disease. Although a normal staining pattern was observed in 28 of 29 biopsy specimens from patients with no evidence of liver disease, the antibody did not bind to hepatocytes in some cases of chronic active hepatitis (2/13), alcoholic liver disease (2/9), haemochromatosis (1/1), cirrhosis (1/2) and liver metastases (2/8). Furthermore, as in a previous study undertaken in the rat, the antibody failed to bind to tumour cells in the single human hepatoma observed in this study. These results suggest that further studies using RL23/36 may shed light on the pathogenesis of a number of liver diseases, including primary hepatocellular carcinoma.
