“…An absorbance was measured and the concentration of RNA was determined using a millimolar extinction coefficient of 570 mM -1 cm -1 at 260 nm. 22 DNA binding was conducted at 15 mM NaCl, 25 mM Tris, pH 7.5. RNA binding was conducted at 50 mM KCl, 50 mM potassium cacodylate, pH 7.0.…”

“…Concentrations of tRNA and 5S RNA were determined by ultraviolet absorption (Al¡s 215). This extinction value is that used for pure tRNA (Lindahl et al, 1965), and it was assumed that 5S RNA would not differ greatly from this value. The concentration of NaCl in MAK column effluents was determined by measurement of refractive indices.…”
