Figure 3.

Real-time detection of the binding kinetics to the "GCG"-sequence immobilised on a glass fibre. Black curve corresponds to the interaction between matching pair of ZF1 and "GCG" motif (k_D: 4,9·10^-3 /s), the red curve corresponds to the ZF2 (k_D: 7,3·10^-3 /s) which should recognise the "AAA" sequence, but not the "GCG".
