Fig. 3From: Comparison of four glycosyl residue composition methods for effectiveness in detecting sugars from cell walls of dicot and grass tissuesDetermination of uronic acid content of AIR from leaves of Arabidopsis, Populus, rice, and switchgrass. Uronic acid assays were carried out using either A H2SO4 or B TFA hydrolysis. Data are means of three technical replicates of each of three biological replicates ± standard deviation, n = 9Back to article page
