“…Several researchers have reported that porous packing materials yield better oligonucleotide separation than their non-porous counterparts [ 20 22 ]. Therefore, we first confirmed whether pore size and the presence or absence of pores affected the separation of long-stranded RNAs.…”

“…Bagge et al [68] systematically investigated the effect of pore size on oligonucleotide separation using RPLC packing materials ranging in pore size from 60 to 300 Å but with identical stationary-phase chemistries and column dimensions (Kromasil C4 150 × 3 mm, 5 μm). The model components were native phosphodiester poly(T) oligonucleotides comprising 5, 10, 15, 20, 25, 30, 40, and 50 units -a socalled poly-T(5-50-mer) sample [68] . The following naming convention was used: a 10-mer deoxythymidine monophosphate with the sequence 5´TTTTTTTTTT-3 ′ was called T10, and so on.…”

“…To achieve a more fundamental understanding of these observations, we decided to build a model that accounts for the accessible surface area, since the main difference between the oligonucleotides in the injected sample is how they enter the pores. A mechanistic model explaining these observations was developed based on a geometric approximation of the rod model inspired by Casassa and combined with a modified equilibrium partition relation accounting for the rod's interaction in the pores (see equations S1and S2 in [68] ).…”

“…Размер и объем пор сорбента определяют удерживание в гельэксклюзионной хроматографии [1,2], предназначенной для разделения олигоили полимерных соединений различных классов, а также и в мицеллярной хроматографии [3]. Для традиционной ВЭЖХ мономерных соединений влияние этого параметра также не исключается [4], хо-тя исследований влияния этой характеристики сорбента на удерживание аналитов при одинаковом химическом составе поверхности сорбента немного [5].…”
