Comparison of TI Ab responses in IUT, TBI, and control mice.
Mice were immunized intraperitoneally with 25 μg of TNP-Ficoll. Sera were obtained 10 days after immunization and tested for IgM and IgG3 anti-TNP levels by sandwich ELISA. Each dot represents an individual mouse. Bar graphs represent average Ab levels ± SD. IUT mice were immunized starting at 12 weeks of age. TBI mice were challenged starting at 12 weeks after transplantation.
