  • Method for capturing analytes eluted from surface-bound ligands
    Patent number: 6844201
    Abstract: Methods for capturing analytes associated with surface-bound ligands are disclosed. The methods involve eluting analytes from surface-bound ligands with a first liquid to generate free analytes, and capturing the free analytes with a solid capturing material within the first liquid to generate a first liquid containing captured analytes. The first liquid may be a flowing liquid or a non-flowing liquid, and the surface to which the surface-bound ligand is attached may be a sensing surface, such as a biosensor, or a non-sensing surface. The captured analytes may be further consolidated at a location removed from the surface-bound ligand, eluted from the solid capturing material with a second liquid, and used for subsequent analysis or procedures.
    Type: Grant
