ADSORPTION COLUMN FOR PURIFYING BODY FLUID
First Claim
1. An adsorption column for body fluid purification comprisinga porous support having a functional group immobilized on a surface of the porous support, the functional group specifically binding to a substance to be adsorbed including at least a low density lipoprotein, whereinthe porous support includes:
- a skeleton made of a silica gel or silica glass having a three-dimensional network structure;
through-pores of an average diameter in a range of 1 μ
m or more to less than 4 μ
m as measured by a mercury intrusion method, the through-pores being formed in voids of the skeleton and having a three-dimensional network form; and
micropores of an average diameter of larger than a maximum length of the substance to be adsorbed in the body fluid purification as measured by a mercury intrusion method, the micropores penetrating from a surface of the skeleton to an inner part thereof and being dispersedly formed.

Abstract
Provided is an absorption column for body fluid purification by which the saturated adsorption amount of a substance to be adsorbed can be increased or the time required for reaching the saturated adsorption can be shortened, and therefore, the column capacity can be considerably reduced and the treatment time can be considerably shortened. The adsorption column having functional groups 6 specifically binding to a substance to be adsorbed including at least low density lipoprotein, immobilized on the surface of a porous support 5. The porous support 5 has double-pore structure comprising: a skeleton 7 made of a silica gel or silica glass having a three-dimensional network structure; through-pores 8 of an average diameter measured by the mercury intrusion method of 1 μm or more but less than 4 μm and having a three-dimensional network structure, which are formed in the voids of the skeleton; and micropores 9 having an average diameter measured by the mercury intrusion method larger than the grain diameter of the substance to be adsorbed, which are dispersedly formed on the surface of the skeleton.
