DNA-Interactive Properties of Crotamine, a Cell-Penetrating Polypeptide and a Potential Drug Carrier
A. Scatchard plot: ν ≡ [crotamine]bound/[total d(CCG)8C]p, L ≡ [crotamine]free. The solid lines represent curves calculated from the best fit of the Tsodikov et al.  modification of the McGhee-von Hippel model for non-cooperative binding ligands  (see Materials and Methods). B. Log-log dependence of the association constants calculated in panel A on [Na+].
