Representative 2D gels of Atlantic cod skin mucus A) Healthy and B) V. anguillarum infected. Annotated spots were identified using LC-MSMS. The mucus proteins were isoelectrically focused on 17cm IPG strips (pI 3–10) in first dimension, run on a 12.5% SDS-PAGE in second dimension and stained with SYPRO Ruby fluorescent dye. Note that the spot numbers correspond to the protein identities outlined in Table 2. N = 6.
