[Spectrophotometric study of the system DNA-lipid].

The effect of some physical and chemical factors on the system DNA-lipid and its components was studied by spectrophotometry. A change of optical density (D) of watersalt suspensions of lipid total fraction in the range of wavelengths from 200 to 350 nm with the change of ionic strength from 0 to 1 M NaC1 and temperature from 20 to 100 degrees C was investigated. Measurements were carried out under various temperature regemes.
