Fig. 9. HPLC profiles showing CS-derived disaccharides (A). The largest peak,
migrating at
4 minutes retention time, represents unsulfated
Di-0S,
followed by the
Di-4S disaccharide. Each tracing represents material
from
40 larvae. (B) CS-derived disaccharides from sotv and
ttv mutants, shown as a percentage of wild-type controls (fraction of
ng disaccharide/mg dry tissue, Ore R control). Unsulfated (
Di-0S) and
monosulfated disaccharides (
Di-4S) across the sotv allelic
series show changes in total CS levels as well as the degree of sulfation.
