Analysis of purified RNA.

(A) Native and (B) denaturing PAGE analysis of fractions collected from Superdex 75 10/300 GL gel filtration. S – concentrated RNA sample after anion exchange chromatography. (C) Analysis of mouse tRNA^Sec by multi-angle static light scattering. The optical density at 260 nm (OD₂₆₀; magenta), Rayleigh ratio (Rq; blue) and differential refractive index (RI; yellow) were monitored during analytical gel filtration on a Superdex 200 10/300 GL column. The measurement was done by Wyatt Technology Europe GmbH.
