Reversed phase HPLC analysis of peptides was performed on
filtered aqueous extracts using a 250 460 mm C18 (5 mm, 110 A)
Chemetex column, according to procedure detailed by Desportes
et al. (2000) modified as follows: Column was eluted at
0.5 mL min1 by a linear gradient of two eluents: A (0.1% Trifluoroacetic
acid in water) and B (0.1% Trifluoroacetic acid in
acetonitrile).Alinear gradientwas developed from 0 to 51% of eluent
B over 65 min, from 51 to 100% of eluent B over 1 min, from 100 back
