Fig. 2. Tetilla mutabilis proteome map, with proteins that were picked for mass spectrometric analysis labeled. Red labels denote proteins that are upregulated during emersion or post-emersion stress, and blue labels denote proteins that are unchanged by emersion stress. The vertical dimension of the 2-D gel represents the molecular mass scale (10–120 kDa on 11% uniform polyacrylamide gels), and the horizontal dimension represents the isoelectric point scale (pH 3–10 on non-linear 24 cm IPG strips).
