Table 1 includes yield and purity data for RNA isolated from varying amounts of rat liver, using the kit. The RNA yields were good, averaging 14 to 122 g for liver quantities between 5 and 40 mg; individual yields reached as high as 141 g. The purity, as determined by the A₂₆₀/A₂₈₀ ratio, was 1.9 or greater (Table 1).

Table 2
Isolation of RNA from Different Cell Lines

RNA was isolated from 2 x 10⁶ cells using the StrataPrep total RNA miniprep kit. Yield and purity were determined by measuring absorbance in 10 mM Tris, pH 7.5.
