“…The preceding paper has reported the use of rabbit polyclonal anti-hEGF antiserum and monoclonal antibody, both raised against hEGF obtained by the synthetic gene method to detect hEGF in normal human salivary glands and their neoplastic lesions (53), and hEGF staining in pleomorphic adenomas have already been reported in detail (36,53,56). The immunohistochemically defined location of hEGF in salivary glands has been controversial; that is; hEGF has been detected in ductal segments (14,44,51,53,56) and in serous acinar compartments (23,27,41). The results are somewhat influenced by tissue fixation, and different antibodies used in these studies (51).…”
