Question

Which of the following is an application of monoclonal antibodies?

• A. Diagnosis or treatment of infectious diseases
• B. Potential use of tumour scanning
• C. Cancer diagnosis
• D. All of the above

Answer 1

The correct option is D All of the above

Monoclonal antibody based products are highly specific for a particular antigen and thus are best diagnostic reagents.

Diagnosis or treatment of infectious diseases is done by detecting the circulatory levels of antigens specific to the infectious agent e.g., antigens of Neisseria gonorrhoeae and herpes simplex virus for the diagnosis of sexually transmitted diseases.

In tumour scanning the monoclonal antibodies are tagged with radioisotope are then injected intravenously into the patients. These gets localize at specific site of tumour which can be detected by imaging the radioactivity and it can differentiate between cancerous and non-cancerous growth, since radiolabeled antibodies are tumor specific.

Monoclonal antibodies makes possible to detect certain cancers at early stages e.g., lung cancer, breast cancer, ovariran cancer, malanoma, colorectal cancer.

So, the correct answer is option D.
