Abstract: A method is provided for immobilizing a ligand, e.g., a nucleic acid, on a solid support. The method includes providing a solid support containing an immobilized latent thiol group, activating the thiol group, contacting the activated thiol group with a nucleic acid comprising an acrylamide functional group, and forming a covalent bond between the two groups, thereby immobilizing the nucleic acid to the solid support. Kits containing the solid supports and method of utilizing the solid supports are also provided.

Abstract: A thin gel for separating and detecting a target molecule, (e.g., an analyte) and methods of use thereof is described. The gel can be optionally reinforced to facilitate removal from an electrophoretic apparatus, wherein the gel matrix comprises immobilized (e.g., covalently bound) capture probes capable of specifically hybridizing with, or binding to, the analyte to be detected. The gel is thin and very short assay times can be achieved facilitating rapid detection of analytes. An assay apparatus is suitable for use with an electrophoretic assay system for the detection of, or separation and detection of an analyte in a biological sample is also described.
