title: RNA partitioning accompanied by adsorption: high-molecular-mass RNA adsorbed at the interface like a particle.
abstract: In a potassium phosphate-poly(ethylene glycol) (PEG) system. RNA partitioning was accompanied by adsorption at the interface, depending on the molecular mass. Low-molecular-mass RNA showed the typical partition behavior of a soluble substance. Conversely, high-molecular-mass RNA was significantly adsorbed at the interface in the potassium phosphate-PEG1500 system. The adsorbed amount was proportional to the added amount, regardless of the phase volume ratio. The partitioning of high-molecular-mass RNA showed an amount-ratio-dependent distribution like that of a particle.
