Unit Summary
This unit covers vaccines, medicines, and monoclonal antibodies for disease prevention and treatment. It explains aseptic techniques, medicine development, and antibody uses. The focus is on ethical considerations, risk evaluation, and societal impacts of scientific advances.
Lesson Summary
You will learn to explain how monoclonal antibodies are produced and describe some ways in which they are used.
Key Notes
- Monoclonal antibodies recognise a specific target, such as an antigen or other biological molecule.
- Monoclonal antibodies are produced by combining a lymphocyte and a tumour cell to produce a hybridoma.
- The hybridoma divides to make many copies of this single clone, which make monoclonal antibodies.
- Monoclonal antibodies are used to detect pathogen antigens & molecules associated with pregnancy, blood clots & cancer.
- Monoclonal antibodies can be attached to radioactive and toxic substances to treat diseased cells, e.g. tumour cells.
Vocabulary To Learn
- antigen: A molecule on the surface of a pathogen or other cell, which triggers an immune response.
- lymphocyte: A white blood cell that is part of the immune system and produces antibodies against a specific antigen.
- monoclonal antibodies: Antibodies produced from a single clone of a hybridoma.
- tumour cell: A cell that undergoes uncontrolled cell division.
- hybridoma: An antibody-producing lymphocyte and a tumour cell fused together.
Common Mistakes To Avoid
- Monoclonal antibodies can act as a 'magic bullet' to deliver medication to certain cells.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Monoclonal antibodies recognise a specific target, such as an antigen or other biological molecule. Monoclonal antibodies are produced by combining a lymphocyte and a tumour cell to produce a hybridoma.
2. Define this scientific word and use it in context. 'antigen'
A molecule on the surface of a pathogen or other cell, which triggers an immune response. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Monoclonal antibodies can act as a 'magic bullet' to deliver medication to certain cells. Correction: The human body is complex and therapies using monoclonal antibodies have had some serious side effects. New treatments should always be treated with caution.
