The proteome complement of Nicotiana tabacum Bright-Yellow-2 culture cells

The Nicotiana tabacum Bright-Yellow-2 (BY2) cell line is one of most commonly used plant suspension cell lines and offers interesting properties, such as fast growth, amenability to genetic transformation, and synchronization of cell division. To build a proteome reference map of BY2 cell proteins, we isolated the soluble proteins from N. tabacum BY2 cells at the end of the exponential growth phase and analyzed them by 2-DE and MALDI TOF-TOF Of the 1422 spots isolated, 795 were identified with a significant score, corresponding to 532 distinct proteins
