    摘要: A method of immobilizing aminated DNA to a substrate surface is provided for use in DNA hybridization assays. The surface can be widely employed in a variety of molded laboratory products including multiwell plates, cell culture dishes, and biological containers. The method comprises the steps of providing a polystyrene substrate having a surface content of between 0.3 and 4.0% atomic percent oxygen, and attaching amine modified oligonucleotide to the surface of the substrate. A resultant product comprising a polystyrene substrate having a surface oxygen content of between 0.3 and 4.0% atomic percent, and a plurality of amine modified oligonucleotides directly attached to the surface of the substrate, is also disclosed.

    摘要: Clinically significant concentrations of digoxin can be determined by reacting an unknown amount of digoxin, a known amount of labelled digoxin, and a composite consisting of anti-digoxin antibodies coupled through an intermediate silane to magnetically responsive particles; magnetically separating the immunochemical complexes formed thereby, counting the radioactivity of either the separated products or remaining solution, and relating the count to a standard curve.
