A Level Biology Antibodies

This comprehensive A‑Level Biology resource covers the Antibodies and Monoclonal Antibodies topic from the AQA specification. Structured as an advanced comprehension activity, it includes clear, exam‑focused revision notes followed by a full set of A‑Level style questions and a detailed, point‑based mark scheme.

Topics covered:

The structure of antibodies, including heavy and light chains, variable and constant regions, hinge region and antigen‑binding sites
Mechanisms of antigen destruction: opsonisation, agglutination, neutralisation, complement activation and antibody‑dependent cell‑mediated cytotoxicity
Monoclonal antibodies: definition, production using hybridoma technology, and reasons for their specificity
Clinical and diagnostic uses of monoclonal antibodies, such as targeted cancer therapies, drug delivery, autoimmune treatments, and pregnancy testing
ELISA and other immunoassay principles, including enzyme‑linked detection and colour‑change outcomes
Ethical considerations, such as the use of animals in antibody production, risks in clinical trials, high treatment costs and issues surrounding accessibility

What’s included:

A full Word document containing high‑level revision notes and 15 structured A‑Level comprehension questions
A separate Word mark scheme document with detailed model answers for each question
A glossary of specialist immunology terms to support independent learning and exam preparation

Perfect for:

A‑Level Biology (AQA) students aiming for high‑grade understanding
Use in revision lessons, intervention groups or independent study
Developing extended‑response exam technique
