Preparation of fusion proteins and CT-conjugates:

…  CT-OVA and CTB-OVA conjugates were produced using the crosslinker N-succinimidyl 3(2-pyridyldithio) propionate, (SPDP). CT (LIST Biological Laboratories), rCTB (provided by Dr. J. Holmgren at the Department of Microbiology and Immunology, University of Gothenburg, Gothenburg, Sweden) and OVA were coupled to SPDP and conjugated as described before [351]. Concentration of the conjugates, and the OVA content, was determined by ELISA against a standard dilution of CT, CTB and OVA. The molar ratio of OVA to CT or CTB was 4:1.
