TABLE 1.

MALDI-TOF MS analysis of the tryptic peptides of the AGP31 Pro-rich domain (P0–P4)

For each peptide, the m/z ratio is indicated, as well as the number of Hyp, hexose, and pentose residues determined by MALDI-TOF MS analysis of AGP31-enriched fraction issued from CEC/NAC and PNA isolation strategies. Samples were excised from SDS-polyacrylamide gels in the 30–40- and 50–60-kDa mass ranges (Fig. 2, lanes 1a, 1b, and 5).

Peptide	m/z	Number of Hyp	Number of hexoses	Number of pentoses
P0	883.52	2	NDa	ND
P1	2163.17	6	1–5	1–2
P2	2218.25	5	1–5	ND
P3	2486.35	6	ND	ND
P4	3476.94	9	1–7	1–2
