Figure 4.

Real-time detection of the binding kinetics to the "AAA"-sequence immobilised on a glass fibre. Black curve corresponds to the interaction between matching pair of ZF2 and "AAA" motif (k_D: 3,5·10^-3 /s), the red curve corresponds to the ZF1 (k_D: 4,6·10^-3 /s) which should recognise the "GCG" sequence, but not the "AAA".
