Method of separating a substance from a liquid

摘要

A liquid containing a separation target substance is brought into contact with a double helix DNA-holding phase to have the separation target substance held by the double helix DNA-holding phase, which is then removed from the liquid. The contact of the double helix DNA with the separation target substance is performed in a liquid medium having a salt concentration of 0.02 mass% or more relative to the total mass of the liquid phase.
