In addition to the reported protein identifications, β-globin and sometimes α-globin were detected in all bands analyzed. For simplicity, these results were omitted from the table.
Protein identifications were considered high-confidence assignments if the TurboSEQUEST browser report matched 3 or more tryptic peptides with a cross-correlation score of 2.5 or higher. Identifications were considered tentative if only 1 or 2 peptides were matched with cross-correlation scores of 2.5 or higher. The number of peptides meeting these criteria is shown.
