Monoclonal Antibodies

The video explains antibodies' role in the immune system, focusing on monoclonal antibodies. These are lab-produced identical antibodies from a single clone of immune cells, known for their high specificity. The production process involves using mice to generate B cells, which are fused with tumor cells to create hybridoma cells. Monoclonal antibodies have various applications, including pregnancy tests and cancer treatment. However, they face criticisms such as high production costs and limited specificity. Despite these challenges, their potential in medicine remains significant, with ongoing research to improve their efficacy and safety.

What is the primary function of antibodies in the immune system?

• To transport oxygen

• To digest food

• To recognize and fight antigens

• To produce hormones

How are monoclonal antibodies produced in the laboratory?

• By cloning T cells

• By fusing B cells with tumor cells

• By mixing different antibodies

• By extracting them from plants

What is a hybridoma cell?

• A cell that digests antigens

• A type of cancer cell

• A fusion of a B cell and a tumor cell

• A cell that produces hormones

In what way are monoclonal antibodies used in pregnancy tests?

• To identify cancer cells

• To detect blood clots

• To bind to the HCG hormone

• To measure blood pressure

What is a major criticism of monoclonal antibodies?

• They have no side effects

• They are too cheap to produce

• They can attack multiple antigens at once

• They are too specific
