Although IEF/SDS-PAGE of the cytosolic proteins showed sufficient resolution, some mitochondrial and basic microsomal membrane-associated proteins were weakly or hardly detectable on the 2D gel. High-quality and -quantity separation of the organelle membrane-associated proteins was accomplished by NEPHGE/SDS-PAGE, the advantage of this method being more critical in tightly membrane-bound proteins that were unwashable with NaCl. These results indicate that NEPHGE/SDS-PAGE is a useful tool for the proteomic analysis of rice membrane-associated proteins.}, pages = {1170--1173}, title = {Technical Improvement to 2D-PAGE of Rice Organelle Membrane Proteins}, volume = {66}, year = {2002} }
