Table 1. Number of proteins identified from adaxial (upper) epidermal peels and mesophyll tissues of the leaves of A. officinalis.

	Average no. of proteins identified (±SE)
Epidermal peels	2189 ± 128
Mesophyll tissues	977 ± 150

Three biological replicates from each type of tissues were prepared and the protein profiles compared using a shotgun approach. Results are presented as mean ± SE.
