Abstract
Stabilized, insolubilized biochemical materials are prepared by covalently bonding a biochemical material such as an antigen, antibody, hormone, or enzyme to a silicic acid heteropolycondensate layer which is applied to a mechanically stable support. The insolubilized biochemical materials are useful as separating agents or adsorbents in radio-immuno assays or affinity chromatography.
