Effect of C. parvum oocyst pre-treatments on the binding of polyclonal anti- Cryptosporidium antibody as determined by ELISA. Oocysts (105 oocysts/well) were tested as control, frozen and thawed six times, boiled for 10 minutes, or incubated at 37°C in 5% bile or in 5% SDS. Error bars represent one standard deviation and fall within the symbols for each point. Signal to noise values above 2 are considered positive. The standard deviation for the noise (PBS control wells) was 0.07.
