Question

Which of the following characteristics should be present in the matrix used for immobilisation?

• A. They are inert
• B. They are insoluble
• C. They should be non-porous
• D. All of the above

Answer 1

The correct option is D All of the above

Immobilisation of enzymes is the process of fixing enzyme to or enclosing it in a solid support so as to use the enzyme in a continuous process. The material which is used for the immobilisation of the enzyme should possess certain characteristics. The material should be inert and should not react with the enzyme molecule. The matrix should be insoluble. This will prevent dissolution of matrix and loss of the enzyme which is entrapped. The matrix should be non-porous to prevent the contamination and loss of enzyme.

Thus, the correct answer is option D.
