The components derived from these preparations were characterised by sodium dodecyl sulphate—polyacrylamide gel electrophoresis, followed by staining or by Western blotting. Surface-exposed polypeptide molecules were also identified by biotinylation. Many protein and glycoprotein molecules were identified in the cell walls. Some of these molecules were immunogenic in man and experimental animals and showed wide variability from species to species. The data suggest that these molecules could be of significance in the diagnosis and pathophysiology of mycobacterial diseases., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-32-4-263
