Abstract: Molecular exclusion HPLC chromatography on a Protein Pak SW 300 column and reversed phase HPLC on a µ-Bondapack Cl8 column were used to purify four novel neurotoxins (rom the crotoxin complex, and five crotoxin subunits (PLA2 and crotapotin) as well as two crotamine isoforms. A single preparative reversed phase HPLC steps yielded a major basic myotoxin followed by the subunits of crotoxin (three PLA2 isoforms and two crotapotin isoforms). This modified procedure may be useful for the rapid, large-scale purification of toxins from Crotalid venoms.
