TABLE 3.
Aberrant disulfide-linked peptides derived from CZA97.012 Env proteinsa

A checkmark indicates that the disulfide-linked peptide was confirmed to be present, and an x indicates that it was not detected. “Minor” indicates that the peptide was identified but at a much lower abundance compared to that of the gp140UNC-Fd-His protein. “Trace” means that the abundance of the peptide was 10- to 100-fold lower than that of the gp140UNC-Fd-His protein.
