Table 1. Binding affinity of PrPC–Ig-LEC12 for selectin–Ig.

After selectin–Ig (experiments 1–3) or PrP–Ig (experiment 4) was immobilized on a CM5 chip through the N-termini, PrP-Ig (experiments 1–3) or selectin-Ig (experiment 4) was flowed through to detect the interactions. Kd values were calculated with either steady-state kinetics (experiments 1–3) or Langmuir method (experiment 4). ND, not determined.
