Producing monoclonal antibodies6 objectives
- Describe how monoclonal antibodies are produced.
- Explain that monoclonal antibodies are produced from a single clone of cells.
- Explain that monoclonal antibodies are specific to one binding site on one protein antigen.
- Explain that mouse lymphocytes can be stimulated to make a particular antibody.
- Explain that lymphocytes are combined with tumour cells to make hybridoma cells that can divide and produce antibodies.
- Explain that single hybridoma cells are cloned to produce many identical cells and that antibodies are then collected and purified.
Uses of monoclonal antibodies8 objectives
- Describe the use of monoclonal antibodies in diagnosis, including pregnancy tests.
- Describe the use of monoclonal antibodies in laboratories to measure hormones and other chemicals in blood or to detect pathogens.
- Describe the use of monoclonal antibodies in research to locate or identify specific molecules by attaching fluorescent dye.
- Explain how monoclonal antibodies can be used to treat some diseases including cancer.
- Explain how a monoclonal antibody can deliver a radioactive substance, toxic drug or growth-inhibiting chemical to cancer cells.
- Explain that students may be asked to work out how unfamiliar monoclonal-antibody tests or treatments work from the information given.
- Explain that monoclonal antibodies can cause more side effects than first expected.
- Evaluate the advantages, disadvantages and ethical issues linked to monoclonal antibodies.

Exam tips
- Understand the Production Process: Use create a flowchart that outlines the steps involved in producing monoclonal antibodies, from the stimulation of mouse lymphocytes to the cloning of hybridoma cells. Link your answer to Producing monoclonal antibodies in Monoclonal antibodies (biology only) (HT only), and keep the biology specific to monoclonal. Link your answer to Producing monoclonal antibodies in Monoclonal antibodies (biology only) (HT only), and keep the biology specific to monoclonal.
- Understand Cloning Process: Use focus on explaining the process of how monoclonal antibodies are produced from a single clone of cells, including the role of hybridoma cells. Link your answer to Producing monoclonal antibodies in Monoclonal antibodies (biology only) (HT only), and keep the biology specific to monoclonal. Link your answer to Producing monoclonal antibodies in Monoclonal antibodies (biology only) (HT only), and keep the biology specific to monoclonal.
Common mistakes
- Misunderstanding the Production Process: Ensure to explain that monoclonal antibodies are produced by fusing mouse lymphocytes with tumour cells to create hybridoma cells, which can then divide and produce the antibodies.
- Misunderstanding Clonal Origin: Emphasize that monoclonal antibodies are derived from a single clone, meaning they are identical and specific to one antigen, which is crucial for their targeted function.
