Biotin-containing monomers and articles formed therefrom
Biotin-containing monomers, polymeric materials formed from the biotin-containing monomers, articles containing the polymeric materials, methods of making the articles, and methods of using the articles are provided. The articles can be used, for example, for affinity capture of biotin-binding proteins, including biotin-binding fusion proteins (i.e., a biotin-binding protein fused to another biomaterial). Articles that contain captured biotin-binding proteins can be further used for affinity capture of various biotin-containing biomaterials such as biotinylated proteins. The articles can also be used, for example, for affinity capture of biotin-binding fusion proteins where the fusion protein includes, for example, an enzyme or antibody.
