Figure 1. Chemical cross-linking of human pGSN.

Figure 1

Panel a: 1-DE analysis of native human pGSN purified from human plasma (G). Lanes represent 1-DE analysis of the same preparation of pGSN after chemical cross-linking with four linkers. Chemical structures and space lengths of respective linkers are presented in panelsc – f. Panel b:Representative MALDI-TOF spectrum of pGSN tryptic digests. Panels c – f represent MALDI-TOF spectra of tryptic digests of pGSN after cross-linking with respective linkers showing significant changes in MALDI-TOF spectra resulting from cross-linking.
