Correction: Modified TCA/acetone precipitation of plant proteins for proteomic analysis (PLoS ONE (2018) 13:12 (e0202238) DOI: 10.1371/journal.pone.0202238

Abstract

S1 Fig. Comparison of 2DE protein profiles of maize embryo proteins extracted using two methods. Shown were two independent experiments. Left panel: The modified TCA/acetone precipitation. Right panel: The classical TCA/acetone precipitation. Spots with increased abundance are indicated in red. About 800 μg of proteins were resolved in pH 4-7 (linear) strip by IEF and then in 12.5% gel by SDS-PAGE. Proteins were visualized using CBB. (TIF) S2 Fig. Comparison of 2DE protein profiles of maize root proteins extracted using two methods. Shown were three independent experiments. Left panel: The modified TCA/acetone precipitation. Right panel: The classical TCA/acetone precipitation. Spots with increased abundance are indicated in red. About 800 μg of proteins were resolved in pH 4-7 (linear) strip by IEF and then in 12.5% gel by SDS-PAGE. Proteins were visualized using CBB.

Right panel: The classical TCA/acetone precipitation. Spots with increased abundance are indicated in red. About 800 μg of proteins were resolved in pH 4-7 (linear) strip by IEF and then in 12.5% gel by SDS-PAGE. Proteins were visualized using CBB. (TIF).
