COVOL: An interactive program for evaluating second virial coefficients from the triaxial shape or dimensions of rigid macromolecules

From: Biophysical Journal | Date: May 1, 1999| Author: | Copyright information

ABSTRACT An interactive program is described for calculating the second virial coefficient contribution to the thermodynamic nonideality of solutions of rigid macromolecules based on their triaxial dimensions. The FORTRAN-77 program, available in precompiled form for the PC, is based on theory for the covolume of triaxial ellipsoid particles [Rallison, J. M., and S. E. Harding. (1985). J. Colloid Interface Sci. 103:284-289]. This covolume has the potential to provide a magnitude for the second virial coefficient of macromolecules bearing no net charge. Allowance for a charge-charge ...
