Mice were injected intra-peritonealy (IP) with 100 μg of either Chicken Ovalbumin (OVA) or peptide 277 (p277) emulsified in CFA (1:1 ratio). Spleens were harvested on day 7 post immunization and T cells were extracted for TCR analysis. in vitro stimulation: T cells from spleens of immunized mice were harvested on day 7 and were re-stimulated with irradiated splenocytes and the relevant peptide antigen. Five of the OVA-immunized mice received a boost IP injection of 100 μg OVA + CFA on day 14, and spleens were harvested on day 60 for TCR analysis (Supplementary file 3).
