2D SDS-PAGE analysis of W64A + and W64A o2 . Non-zein proteins from W64A + (A) and W64Ao2 (B) lines were extracted from mature endosperm flour and separated by 2D SDS-PAGE. Circled, numbered spots were excised from gels and protein identities were determined by MALDI-TOF peptide mass mapping and correspond to the rows in Table 1.
