    • D in the μm range
    • For the binding of LL to Fyn SH3, Li et al. (Ref. ) reported a dissociation constant of 25 nM at 4 °C, which was determined by equilibrium dialysis using fluorimetric detection of the highly fluorescent LL ligand. Because the LL ligand is highly lipohilic, it may possibly bind to the dialysis cassette in an unspecific manner. In fact, our own measurements showed that the LL ligand binds to Fyn SH3 only with a KD in the μm range.
