From: Cold shock CspA and CspB protein production during periodic temperature cycling in Escherichia coli
The degradation of CspA-FLAG and CspB-FLAG. Western blot assay after five hours of incubation when cells had completed three temperature cycles (A), and a graphical representation of the degradation of CspA-FLAG (empty squares) and CspB-FLAG (full squares) are shown (B). The amounts of proteins are plotted relative to the amount prior to the addition of spectinomycin. The data were obtained from three independent experiments. Mean values and standard deviations are given.
