The question of low-abundance proteins from biological tissues is still a major issue. Technologies have been devised to improve the situation and in the last few years a method based on solid-phase combinatorial peptide ligand libraries has been extensively applied to animal extracts. This method has also been extended to plant extracts taking advantage of findings from previous experience. Detailed methods are described and their pertinence highlighted according to various situations of plant sample origin, size of the sample, and analytical methods intended to be used for protein identifications.
