Table 5 also shows that the maximum phenol extraction recovery was reached using methanol, followed by ethanol (more than 90% for both solvents) and acetone.
The system is readily automated and it eliminates the need for phenol extraction, DNase treatment, ethanol precipitation, columns, vacuum manifolds and centrifuge steps.
After the reaction mixture was treated with 1 U of RNase-free DNase at 37[degrees]C for an additional hour, synthesized mRNA was purified with one round of phenol extraction followed by ethanol precipitation.
After centrifugation at 8000g at 4[degrees]C for 5 min, supernatant solutions were transferred to fresh tubes, and phenol extraction was repeated for an additional one to three times until no debris was found in the interphase, followed by ethanol precipitation.
