The effect of phospholipase A 2 (PLA 2 )-filled bioreactor on the cholesterol level of hypercholesterolemic New Zealand white rabbits was characterized. Bioreactors were constructed by immobilizing the enzyme to beads with amino residues and packing the beads with the enzyme into the hollow fiber. Enzymatic activity was monitored by titrating the reaction between PLA 2 and the substrate L-alpha-phosphatideylcholine dipalmitoyl with sodium hydroxide.
