Water soluble toxin produced by pfiesteria species

摘要

An isolated and purified Pfiesteria toxin having the NMR spectra given in FIG. 1 herein is described. The toxin may be produced by (a) culturing a Pfiesteria species in a growth media to produce Pfiesteria toxin therein; (b) separating a first fraction of organic compounds including said Pfiesteria toxin from said growth media; and then (c) separating a second fraction consisting essentially of said Pfiesteria toxin from said first fraction by chromatography with porous silica beads.
