Meaning and Definition
An antibody produced by a single clone of immune cells, designed to bind specifically to a single target protein or antigen.
In medicine and biotechnology, a laboratory-made protein used as a targeted therapy to treat diseases such as cancer, autoimmune disorders, and infections. These are mass-produced from identical immune cells, allowing for precise, consistent therapeutic action against specific molecular targets.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Pronunciation differs slightly (see IPA). Spelling conventions for related terms may apply (e.g., tumour/tumor, leukaemia/leukemia) but not to the term itself.
Connotations
Identical. Associated with advanced medicine, biotechnology, and high-cost treatments in both regions.
Frequency
Frequency is comparable in medical/scientific contexts. Public awareness increased similarly in both regions due to high-profile treatments (e.g., for COVID-19, cancer).

FAQ
Frequently Asked Questions
They are laboratory-manufactured, though they are designed to mimic or enhance the body's natural antibody response. They are not harvested directly from human or animal blood in a polyclonal mix.
Primarily for targeted therapy in conditions like cancer (e.g., trastuzumab for breast cancer), autoimmune diseases (e.g., adalimumab for rheumatoid arthritis), and increasingly in infectious diseases (e.g., some COVID-19 treatments). They are also vital research tools in laboratories.
Vaccines stimulate your own immune system to produce a protective response (active immunity). Monoclonal antibodies provide ready-made, temporary antibodies directly (passive immunity) or deliver a targeted drug payload to specific cells.
Their development is complex, time-consuming, and involves sophisticated biotechnology. Manufacturing requires living cell cultures in sterile bioreactors, and purification processes are stringent, leading to high production costs.
An antibody produced by a single clone of immune cells, designed to bind specifically to a single target protein or antigen.
Monoclonal antibody is usually technical, medical, scientific, academic, journalistic (within health/science reporting) in register.
