im·mo·bi·lized en·zyme

an enzyme that has been bound, usually covalently, to an insoluble organic or inorganic matrix or has been encapsulated.

immobilized enzyme

An enzyme fixed by physical or chemical means to a solid support–eg, a bead or gel to confine a reaction of interest to a particular site

Recent Advances and Applications of Immobilized Enzyme Technologies: A Review.
The catalytic activity of the immobilized enzyme was determined by mixing 1 g of catalytic P (AN-co-MMA) nanoparticles with 50 mL of 100 mM lactose in phosphate-citrate solution (pH 4.
Magnetic beads [17] have been used to immobilize yeast invertase, and the separation experiment of immobilized enzyme from substrate was easy to operate.
This process was the first large-scale industrial use of an immobilized enzyme (Vieille and Zeikus 2001).
The activity of both free and immobilized enzyme was measured using spectrophotometer at 410nm.
For technological and economical reasons, industrial processes have to be done by using immobilized enzyme derivatives.
can provide reproducible digestions in minutes through automation, optimized buffers and trypsin immobilized enzyme reactors (IMERs).
Soluble and immobilized enzyme has been evaluated for the hydrolysis of lactose from milk and whey in batch process at 50[degrees]C.
Apart from the classical electrochemical (usually amperometric) biosensors based on the immobilized enzyme, biosensors that are based on the immunochemical principle with the piezoelectric detection and the possibility of the antigen immobilization on the surface of a piezoelectric crystal prevail.
The specific activity of the free was compared to that of the immobilized enzyme.
