Figure 2From: Proteomic analysis of the response of the plant growth-promoting bacterium Pseudomonas putida UW4 to nickel stress A preparative gel of P. putida UW4 control proteins. About 1 mg of protein samples were loaded onto IPG 4–7 strip in the first dimension, and separated using 12% SDS-PAGE gel in the second dimension. Proteins spots were visualized by Coomassie staining. The 35 identified and labeled spots are annotated according to the numbering in Table 2.Back to article page
