Publication number: 20030215806Abstract: The present invention provides a method and reagent composition for attachment of target molecules onto the surface of a substrate, such as microwell plates, tubes, beads, microscope slides, silicon wafers or membranes. In one embodiment, the method and composition are used to immobilize nucleic acid probes onto plastic materials such as microwell plates, e.g., for use in hybridization assays. In a preferred embodiment, the method and composition are adapted for use with substantially flat surfaces, such as those provided by microscope slides and other plastic, silicon hydride, or organosilane-pretreated glass or silicone slide support surfaces. The reagent composition can then be used to attach a target molecule such as a biomolecule (e.g., a nucleic acid) which in turn can be used for specific binding reactions (e.g., to hybridize a nucleic acid to its complementary strand).Type: ApplicationFiled: May 9, 2002Publication date: November 20, 2003Inventor: Mark A.
