- the polymer carrier according to the present invention to which a predetermined zinc complex group is bound, under certain conditions, Since it binds to an anionic substituent (for example, a phosphate group) and is poorly solvent-soluble (preferably solvent-insoluble) as a whole, it is easy to separate and purify a substance having the substituent, and it is safe and inexpensive. Become. Further, the use of the polymer carrier provides a capture device that enables simple separation and purification with a filter, and a rapid and easy capture method of binding under a neutral condition and then dissociating under a constant condition.
- an anionic substituent for example, a phosphate group
