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.

Oxidized styrenic polymers for DNA binding

A method of attaching dialdehyde starch to surfaces is disclosed. A substrate to which substances may be coupled, which substrate comprises at least one surface coated with dialdehyde starch, and products produced utilizing the substrate are also provided.

A method for making a semi-permeable microporous polymer sheet, useful as a separation membrane or the like, including extruding a melt-blended mixture of a high-temperature thermoplastic polymer and a leachable glass to form sheet and then leaching the glass from the sheet to leave a microporous relict polymer network, wherein the permeability of the sheet is improved by plasma-etching the surface of the sheet before or after leaching. Hydrophilic or hydrophobic porous membranes may be provided.

Method for making semi-permeable polymer membranes

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.
