Figure 4

Comparisons of Chesapeake Bay metaproteomes. (a) Independent samples from Station 804, 804a and 804b; (b) Station 804a vs. Station 707; (c) Station 804a vs. Station 858; (d) Station 707 vs. 858. Image overlays were constructed with Compugen Z3 software. Spots circled in red are unmatched, those in yellow and blue are differentially expressed at a level of ≥ 3-fold between images. No unmatched or differential spots are shown in c and d because software based matching of these images failed. Red marks in panels c and d are alignment points used to produce the pictured overlay. Quantitative results of matching are reported in Table 1. Total 100 μg proteins are loaded on each polyacrylamide gel and the gels are stained by SYPRO Ruby. pI, isoelectric point; Mr, molecular weight.
