Fig. 5From: Comparison of grain protein profiles of Brazilian cowpea (Vigna unguiculata) cultivars based on principal component analysisPCA plots of 297 matched spots volume (%Vol) of 12 2-DE gels from grains of four Brazilian cowpea (Vigna unguiculata) cultivars. (A) BRS Aracê, (I) BRS Itaim, (P) BRS Pajeú, and (X) BRS Xiquexique. Numbers 1, 2, and 3 refer to the triplicate of each cultivar gels. Proteins were separated by 2-DE SDS-PAGE using 13 cm pH 4–7 IPG stripsBack to article page
