At high salt concentrations, the mRNA containing poly(A) tails binds to the complementary oligo(dT) molecules of the affinity column, and so, mRNA will be retained; all other RNA molecules can be washed through the column by further high salt solution. finally, the bound mRNA can be eluted by using
