Trouble removing contaminating proteins from amylose resin

I wish they published more about the actual composition of the amylose resin
and the specific chemistry of the linker. The amylose resin is indeed
somewhat strange, however we have in the past used beta octyl glucoside (but
not dodecyl maltoside, for obvious reason!) with it and everything was OK.
In your case, if your parasite proteins bind really tightly then you
probably will end up with some serious additional purification - try HIC yet

Good luck,
