Monoclonal antibodies can bind to tumour markers (antigens on cancer cells) and deliver anti-cancer drugs to the specific cells instead of all round the body
Monoclonal antibodies are used in pregnancy tests
Used in ELISA tests
Direct ELISA test- uses a single antibody that is complimentary to the antigen you are testing for
Indirect ELISA test- uses two different antibodies
ELISA test:
antigens in a well
add bodily fluid (if antibodies are present, they'll bind to the antigen)
Monoclonal antibody is added, which binds to the human antibody
Substrate is added and changes to a coloured product by the enzyme
Herceptin monoclonal antibodies can be used to prevent the growth and division of breast cancer
