Table 1. Identification of the HPA binding proteins, affinity purified and separated by 2-DE, identified using MALDI-MS.

The protein accession number, description, MASCOT score, sequence coverage, nominal mass and predicted pI are indicated. Fold change is the ratio between the mean normalised volume of the spot separated by 2-DE from the LN+ve group and the LN-ve group.
