Images of two 2D electrophoresis gels.

<p>Crude protein extracts (600 µg) were separated on strips pH 4–7 and SDS-PAGE on 15% polyacrylamide gradient gels. Spots with significant differences in expression level are marked on the gel: <i>E. coli BL21/pACYC184</i> cells (A) untreated and (B) treated with K₂TeO₃, and <i>E. coli BL21/pLK18</i> cells (C) untreated and (D) treated with K₂TeO₃.
