Figure 4. Mass Spectrometry identified complement peptides C3c and C3d in membrane fractions of Jurkat cells treated with amine-terminated PAMAM dendrimers.

Figure 4.

Jurkat cells were either untreated or treated with 10 mg/mL of amine-terminated PAMAM dendrimers for one hour. The membrane fractions were isolated and analyzed by mass spectrometry as described in materials and methods. (A) Identification of the tryptic peptide NTMILEICTR corresponding to the human C3d complement split product. (B) Identification of the tryptic peptide DICEEQVNSLPGSITK corresponding to the human C3c complement split product. Each peak represents a corresponding fragment ion.
