CDR3 sequences. Sequencing analysis of two clones with identical VβJβ combinations from PLPtg/PD-1-/- mice A and B and of one clone with a different VβJβ combination from mouse A. Note identical TCRVβ and TCRJβ regions surrounding the CDR3 region, which not only differs in aminoacids but also, more importantly, in length, thus indicating recognition of different antigens.
