Abstract
Equilibrium binding properties of DAPI and Hoechst for prototype curve d (CA(4)T(4)G)(n) and straight (CT(4)A(4)G)(n) DNAs were derived from fluorescence intensity. Both decamers display a single strong binding site for each ligand. Hoechst binds seven times stronger to curved tha n to straight DNA. An additional cooperative, much weaker binding site is found for DAPI. (C) 1997 Elsevier Science B.V.
