Proteins differentially present in the serum of childhood- and adult- onset Crohn’s disease.

Protein name	Protein symbol	MW	pI	Mascot score	Coverage	Expression levels

Clusterin	CLUS_HUMAN	53031.00	5.90	96	34	5.55	54.3*
Apolipoprotein B-100	APOB_HUMAN	516651.00	6.60	352	29	471.1*	21.6

Differentially expressed proteins in all samples of each patient group present with their name and symbol, theoretical pI and molecular weight calculated using the CalPI/MW available on the Swiss-Prot Web site. MASCOT search score, and coverage of each identification are also listed. Score is −10 Log (p), where p is the probability that the observed match is a random event. Scores N55 indicate identity or extensive homology at the p < 0.05 level. Expression levels were calculated in relation to control densities. Expression level >1 indicates overexpression, expression level <1 indicates suppression.
