Effect of solvent on the optical behavior of macromolecules in a laminar flow

Publikováno v: Journal of Polymer Science Part C: Polymer Symposia. 16:1001-1009

The segmental anisotropy of a series of macromolecules in different solvents was measured by means of streaming birefringence and viscosity. It is shown that the measured segmental anisotropy (α1 — α2) substantially depends on properties of the s

It was shown that gamma-irradiation of water-ethanol and water-n-propanol solutions of DNA with doses of 10-30 Gy leads to a fall of the specific volume of the macromolecule upon the cooperative transition at a critical concentration of alcohol in so

Publikováno v: Biofizika. 42(1)

In this work we had assumed to clarify the role of the water structure in the process of the radiation damage of DNA. It is known that the aliphatic alcohols stabilize the water structure until the critical concentration. In this connection we have a

[Study of the interaction of a DNA molecule with coordination compounds of divalent platinum. I. Effect of cis-diaminodichloroplatinum on molecular parameters of DNA in solution]

Autor: N A, Kas'ianenko, S V, Valueva, N A, Smorygo, S A, D'iachenko, E V, Frisman

Publikováno v: Molekuliarnaia biologiia. 29(2)

DNA interaction with cis-diaminodichloroplatinum (cis-DDP in solutions of different ionic strength was studied by flow birefringence, viscometry, circular dichroism. Though cis-DDP is not an electrolyte, electrostatic interactions are important for b

[Hydrodynamic and optical behavior of DNA molecule in the range of high ionic strength]

Autor: E V, Frisman, N A, Kas'ianenko

Publikováno v: Molekuliarnaia biologiia. 24(2)

The hydrodynamic and optical properties (intrinsic viscosity and optical anisotropy of DNA) have been studied at the high ionic strength mu greater than or equal to 1 M. It has been shown that the effective volume of DNA molecule doesn't depend of mu
