shows the staining patterns in SDS polyacrylamide gels of the DPs and APs of the
various bacterial extracts before and after proteolytic digestion. While Coomassie staining was specific for proteins, silver staining revealed both the presence of polysaccharides and proteins. Table 1 gives the protein amounts and concentrations for the various bacterial extracts.Generally, the protein amounts varied between bacterial species, as can be seen in Table 1 for
