Abstract
Two ribonuclease A bioreactors based on lab-made macroporous monolithic columns and intended for polynucleotide degradation were prepared using in situ free-radical polymerization. Different methods of enzyme immobilization were applied. In the first case, the biocatalyst molecule was attached to the solid surface via direct covalent binding, while in the second bioreactor the flexible-chain synthetic polymer was used as an intermediate spacer. The effect of temperature, substrate flow rate, and loaded sample volume on the biocatalytic efficiency of the immobilized enzyme was examined. The kinetic parameters of the enzymatic degradation of synthetic polycytidylic acid were calculated and compared to those found for hydrolysis with soluble ribonuclease A. The monitoring of substrate splitting was carried out by means of fast anion-exchange HPLC on an ultra-short monolithic column (disk) using off- and on-line analytical approaches.
