Fig. 4. Effect of acidification on post-HPLC separated products generated from
ionophore-challenged barnacle seminal vesicles/testes. (A) The original
RP-HPLC separation at pH 7.0 and the fractions collected (green, blue and
yellow regions) that were subsequently acidified to pH 3.5, re-extracted and
separated again by RP-HPLC at pH 7.0 (B-D).
