The disease state, cow identity and months post infection (mpi) identify the sample. Dyes and gels were randomly assigned to the 4 biological replicates of infected and control cows to minimize the influence of dye bias and gel to gel variation. The 2 infected samples marked NA were either not collected (cow 52, 24 mpi) or no suitable gel image was obtained (cow 38, 0 mpi)
