re-evaluation of the factors ( e.g . ficoll concentration , temperature , and ratio of the diatrizoate salts ) which affect these separations showed that under our conditions it was advantageous to use a medium with a lower viscosity ( ficoll concentration ) and/or a higher osmotic strength ( increased sodium diatrizoate : meglumine diatrizoate ) than had been recommended previously ( ferrante and thong , 1978 ; 1980 ; ferrante et al. , 1982 ) .
