Differentially expressed protein spots identified from the 2D-DIGE profiling of human plasma, with higher abundance in neonates and children compared to adults.

<p>Proteins were identified using MALTI-TOF/TOF. IPI – International Protein Index accession number. Protein spots 1–11 were identified from pH 3–11 gels; Protein spots 12–19 were identified from pH 4–7 gels. Protein score reflects the combined scores of all observed mass spectra that can be matched to amino acid sequences within a specific protein; higher score indicates a more confident match.
