Magnetically responsive reagent carrier and method of preparation. |
摘要 |
<p>A stable magnetically responsive, substantially remanence-free reagent carrier comprises an iron oxide colloidally dispersed in a smooth particulate polymeric matrix having preferentially a hydrated diameter of from about 0.5 to about 100 mu m. The reagent carrier is prepared by a process which includes incorporating iron salts by passive transport into substantially spherical, water-swellable polymeric matrices, converting in situ the iron salts so-incorporated into their respective iron oxides. The carrier with a reagent attached thereto is useful inter alia in immunoassays.</p> |
