Enhanced affinity matrices with enhanced visibility for molecular drag and immunoprecipitation applications

摘要

An affinity matrix for the isolation of a molecule from an aqueous solution, the affinity matrix comprising a particulate polymeric support containing a mixture of particles, wherein a first fraction of particles in the mixture have a covalently linked dye for allow the optical detection of the polymeric support, and a second fraction of particles in the mixture have an affinity ligand other than the bound dye for the capture of the molecule, where none of the particles in the mixture contain both the dye and the ligand of affinity
