Summary for Patent: 4,268,423
Title: | Support matrices for immobilized enzymes |
Abstract: | An improved method of preparing support matrices for immobilization of reactive chemical entities, such as enzymes, comprises deposition of a polyamine on a core support, such as an inorganic oxide, contacting the polyamine-coated core support with a bifunctional reagent which cross-links the polyamine and provides pendant functional groups, and recovering the matrix, wherein the improvement comprises deposition of the polyamine as a thin, uniform film from solvents of low surface tension. |
