The affinities of TCR0 and TCR15 for the vrt1-pHLA and vrt0-pHLA*

TCR no.Ka (1/Ms)Kd (1/s)KD (M)KD-TCR0/KD-TCR15
Binding to the vrt1-pHLA
TCR0 (WT)4.91E+052.68E+005.46E−061.0
TCR154.19E+052.99E−017.14E−077.6
Binding to the vrt0-pHLA
TCR0 (WT)3.58E+057.76E−012.17E−061.0
TCR154.28E+051.67E−013.90E−075.6
  • *The affinities of the TCRs were determined with Biacore 4000, and the change over the affinity of the wild-type molecule TCR0 is indicated.

  • pHLA, peptide-HLA complexes; TCR, T-cell receptor; WT, wild-type.
