Figure 2From: Cold shock CspA and CspB protein production during periodic temperature cycling in Escherichia coli2DGE gel of total cell protein from E. coli during periodic temperature cycling. Two dimensional gels of E.coli lysates obtained during constant incubation at 37°C (A), periodic temperature cycling (B), and at 8°C (C). The pI range is 4–7 and the molecular mass range is 10–250 kDa. The identity of protein spots that were significantly (p>0.05) up or down produced relative to the proteins in cells constantly incubated at 37°C are given in Table 1.Back to article page
