We need some advise/help on purification of cryptosporidium cysts from
calf stool for the purpose of injection for antibody production.  Our
source material is a 10% formalin preserved prep of calf stool "rich" in
Crypto oocysts.  We have tried CsCl and Ficol gradients with only limited
success.  Open to any and all suggestions for other approaches.

Thanks in advance
