Abstract

The present invention provides a porous cellulose gel having a high mechanical strength capable of being operated at a higher flow rate, and a method for producing the same. To a suspension liquid of cellulose particles, a crosslinking agent in an amount of from 4 to 12 times the amount of the cellulose monomer in terms of moles and an alkali in an amount of from 0.1 to 1.5 times the amount of the crosslinking agent in terms of moles are added continuously dropwise or added dividedly over a prescribed period of time, whereby flow rate characteristics of a resulting porous cellulose gel can be enhanced. According to the invention, the production efficiency of a polymer substance, such as a nucleic acid and a protein can be enhanced.
