Provided is a lens solution which has excellent lipid detergency, exhibits high hydrophilization performance, and exhibits an excellent lipid adhesion preventive effect and an excellent lubricity-imparting effect when the solution is used to coat a lens. Disclosed is a lens solution containing a polymer having 2.5% to 95% by mass of the following repeating unit (A) and 2.5% to 95% by mass of the following repeating unit (B):

Lens solution, contact lens, and production method therefor

Provided is a cell adhesion inhibitor which exhibits low cytotoxicity and an excellent cell adhesion prevention effect; a tool and an apparatus each having a surface modified through application of the cell adhesion inhibitor thereto; a method for producing each of the surface-modified tool and apparatus; a biomedical structure and a production method therefor; and a microchannel device and a production method therefor. The invention provides a cell adhesion inhibitor comprising, as an active ingredient, a polymer comprising a repeating unit having a sulfinyl group in a side chain thereof.

Cell adhesion inhibitor

Provided is a filler for affinity chromatography having a high dynamic binding capacity for proteins and having excellent alkali resistance and storage stability. The filler for affinity chromatography of the present invention comprises a porous particle consisting of a copolymer of 40 parts to 99.5 parts by mass of (M-1) a methacryloyl group-containing vinyl monomer that contains a hydroxyl group and does not contain an epoxy group, 0.5 parts to 30 parts by mass of (M-2) an epoxy group-containing vinyl monomer, 0 parts to 59.5 parts by mass of (M-3) a methacryloyl group-containing vinyl monomer which is other than the monomers (M-1) and (M-2), and 0 parts to 25 parts by mass of (M-4) a vinyl monomer other than the monomers (M-1), (M-2) and (M-3) (with the proviso that the total amount of the contents of (M-1), (M-2), (M-3) and (M-4) is 100 parts by mass); ring-opened epoxy group obtainable by ring-opening of epoxy group that is contained in the copolymer; and ligand that is bound to the porous particle.

Filler for affinity chromatography

Provided is a filler for affinity chromatography which is useful for protein purification and contains porous particles that have a high dynamic binding capacity for proteins and excellent pressure characteristics. The filler for affinity chromatography of the present invention is characterized in that it includes a porous particle consisting of a polymer of vinyl monomer including a cross-linkable vinyl monomer that contains hydroxyl group but does not contain epoxy group and an epoxy group-containing non-cross-linkable vinyl monomer, or a cross-linkable vinyl monomer that contains hydroxyl group and epoxy group, ligands bound to the porous particle, and ring-opened epoxy groups.
