  • Preparing a reactor containing enzymes attached to dialdehyde cellulose
    Patent number: 4013514
    Abstract: Water-insoluble, biologically active conjugates for use in a reactor core of a flow-through reactor are prepared by covalently bonding an enzyme directly to a fibrous dialdehyde cellulose such as cotton. Preferably the fibrous cellulose is placed in the reactor core of a flow-through reactor before or after it is treated with periodic acid solution to convert glucose units thereof to units containing dialdehyde groups. Thereafter, an enzyme solution is passed through the resultant dialdehyde cellulose to bind the enzyme to the cellulose.
