Question

Which of the following synthetic polymers are used for immobilisation of enzymes?

• A. Diethylamino ethyl cellulose
• B. Polyvinyl chloride
• C. Polyethylene glycol
• D. All of the above

Answer 1

Answer: (D)

All of the above

Immobilization of enzyme is a process by which enzymes are attached to an inert, insoluble material. This increases resistance to changes in conditions such as pH or temperature. Synthetic polymers are basically ion exchange resins that are insoluble in water, so they can make a good support or matrix for enzyme immobilisation. They also have a porous surface, hence they can easily hold the enzyme or cells. Some examples of synthetic polymers are diethylamino ethyl cellulose (DEAE), polyvinyl chloride (PVC), UV activated polyethylene glycol (PEG).

So, the correct answer is option D.
