    2016-8-9 · A 20-mer oligonucleotide is typically recovered in a 80 % yieldafter 3 hours of rotary shaking thereby making this technique comparableto electroelution. Since elution isa diffusion-controlled process, more buffer will aid in elution efficiency.Also, note that longer oligonucleotides will take longer to diffuse fromthe gel.
