Immobilized ribonuclease and alkaline phosphatase

An insoluble, solid matrix carrying simultaneously several different enzymatic functions, is constituted by the conjoint association by irreversible binding on a previously activated matrix support, of a nuclease selected from the group of ribonucleases A, T1, T2, U2 and an alkaline phosphatease.

Beschreibung
Zusammenfassung:	An insoluble, solid matrix carrying simultaneously several different enzymatic functions, is constituted by the conjoint association by irreversible binding on a previously activated matrix support, of a nuclease selected from the group of ribonucleases A, T1, T2, U2 and an alkaline phosphatease. Free activated groups of the matrix after binding of the enzymes, are neutralized by a free amino organic base. The support is selected from among non-denaturing supports effecting the irreversible physical adsorption of the enzymes, such as supports of glass or quartz beads, highly cross-linked gels of the agarose or cellulose type. Polymers AnUOH, AnCOH, AnGOH and/or oligonucleotides U, C, A or G, of predetermined lengths, can be obtained by fractionating the polyribonucleotides by incubation with the insoluble solid matrix.
