Abstract
The present invention aims to provide a material for adsorbing soluble tumor necrosis factor receptors with high efficiency. The present invention provides an adsorbing material for soluble tumor necrosis factor receptors, which includes a superficially porous water-insoluble polymeric material, wherein the pore size distribution curve for the surface of the water-insoluble polymeric material, which is derived from a distribution of melting points determined by differential scanning calorimeter, shows the peak radius in the range of 1 to 80 nm, and the water-insoluble polymeric material has a zeta potential at pH 7.4 of −15 to 15 mV, and the water-insoluble polymeric material is in fiber, particle, or film form.
