Figure 1

2D protein gels from Daphnia pulex acclimated at 20°C (A) and 10°C (B). Gel images represent fusion (average) images from a set of three (A) or two (B) biological replicates. Consensus spots used for comparison in (D) are encircled. Blue and red numbers indicate cold-repressed and cold-induced protein spots that were picked from the 2D gels for mass-spectrometric analysis. Black numbers indicate previously identified proteins [12]. (C) Dual-channel representation of the gel images shown in (A) and (B). Protein spots of similar expression intensity appear in yellow. Green indicates that spots are much stronger or unique on the gel from 20°C-acclimated animals, whereas red means that spots are much stronger or unique in the gel from 10°C-acclimated D. pulex. (D) Scatter plot showing the comparison of expression levels in the two fusion images (Vrel: relative spot volume).
