Four protocols viz., the trichloroacetic acid-acetone (TCA), phenol-ammonium acetate (PAA), phenol/SDS-ammonium acetate (PSA), and trisbase-acetone (TBA) were evaluated with modifications for protein extraction from banana (Grand Naine) roots, considered as recalcitrant tissues for proteomic analysis. The two-dimensional electrophoresis (2-DE) separated proteins were compared based on protein yield, the number of resolved proteins, the sum of spot quantity, average spot intensity, and proteins resolved in the 4-7 pI range. The PAA protocol yielded more proteins (0.89 mg/g of tissues) and protein spots (584) in the 2-DE gel than TCA and other protocols. Also, the PAA protocol was superior in terms of the sum of total spot quantity and average spot intensity to TCA and other protocols, suggesting phenol as extractant and ammonium acetate as a precipitant of proteins were the most suitable for banana rooteomics analysis by 2-DE. In addition, 1:3 ratios of root tissue to extraction buffer and overnight protein precipitation were the most efficient to obtain maximum protein yield.
