For the small scale chromatography the dialyzed
phycobiliproteins-containing solution was
applied to a column (15.0×2.5 cm) of DEAE–
cellulose, pre-equilibrated with 50 mM acetate
buffer (pH 5.5). After washing with 200 ml of
starting buffer (50 mM), the column was developed
with 200 ml of 0.25 M acetic acid–sodium
acetate buffer (pH 5.5). The column was then
developed with 300 ml of 0.35 M acetic acidsodium
acetate buffer (pH 5.5). The flow rate was
maintained at 100 ml h−1 (0.34 ml cm−2 min−1)
until the eluate became coloured. The eluate was
collected in 2.5 ml fractions.
For the large scale chromatography the dialyzed
phycobiliproteins-containing solution was
applied to a column (15.0×9.0 cm) of DEAE–
cellulose, pre-equilibrated with 50 mM acetate
buffer (pH 5.5). After washing with 800 ml of
starting buffer (50 mM), the column was developed
with 800 ml of 0.25 M acetic acid–sodium
acetate buffer (pH 5.5). Then, the column was
developed with 1000 ml of 0.35 M acetic acid–
sodium acetate buffer (pH 5.5). The flow rate was
