Scatchard plots of AIC:DNA binding. (a) The curve of AIC binding to G-c-Myc (Pu18) registered by UV absorption (triangles) and spectrofluorimetry (squares). The circles represent absorption of nonfluorescent complexes. (b) The curve of AIC binding to G-tel registered by UV absorption (triangles) and spectrofluorimetry (squares). (c) The curve of AIC binding to Pu18 c-Myc duplex registered by UV absorption. The parameters and were calculated per DNA strand: Hanks’ buffer, °C.
