Fig. 2From: Proteomic changes in the xylem sap of Brassica napus under cadmium stress and functional validationSeparation of xylem sap proteins by SDS-PAGE. Proteins from the xylem sap were concentrated then separated by SDS-PAGE. The gel was stained with Coomassie brilliant blue. M are protein molecular mass markers (kDa). CK-1, CK-2, CK-3, Cd-1, Cd-2, and Cd-3 represent biological replicates xylem sap samples from control and Cd-treated Brassica napus plants respectivelyBack to article page
