## Abstract With increasing addition of __Escherichia coli__ LPS to calf thymus DNA, both dissolved in CaCl~2~, absorption maxima of DNA at 260 nm decreased gradually with the appearance of isosbastic points at both ends of spectra, which implied some binding between DNA and LPS. Hill plot of absor
