Differential expression of albumins and globulins of wheat flours of different technological qualities revealed by nanoUPLC-UDMS.

Soluble proteins were extracted from common wheat flour obtained from nine cultivars of different qualities and were analyzed by nanoUPLC and Ultra Definition Mass Spectrometry (UDMS) label-free quantitative approach. Collectively, 5894 proteins were identified and quantified with 8 peptides/protein. A total of 414 proteins were found differentially expressed with 85% proteins not yet described in the literature, according to their biological function.
