Figure 3. Mass Spectrum for a Peptide Isolated from the Trypsin Digest of Δ41-52 hPRL.

Figure 3

Dimeric Δ41-52 hPRL was isolated by size exclusion chromatography, digested with trypsin, and submitted to LC/MS/MS as described in the Materials and Methods section. The disulfide-linked peptides constituting residues 10-16 was identified by both the mass of the peptide fragment and the sequence information.
