Monoclonal Antibodies Flashcards
what are monoclonal antibodies
antibodies produced from a single type of cloned cell, specific to one binding site on one antigen
what can they be used for(3)
1) detect pathogens
2) treating diseases
3) identify specific molecules being investigated
why are mice used to get MCA(3)
1) small (cab house large number of them -> practical )
2) fast reproduction rate (lots of mice)
3) cheap to keep (lower research costs)
step 1 of making MCA with mice
inject mouse with antigen complimentary to antibody you want to make ; mouse will start an immune response and produces monoclonal antibodies complimentary to antigen
step 2 of making MCA with mice
lymphocytes combined with particular type of cancer cells as rumours clone rapidly ; new cells divide outside of body to make MCA
step 3 of making MCA with mice
Hybrid in as are checked to ensure they have the correct MCA and cloned to make large numbers of identical cells
step 4 of making MCA with mice
large amounts of MCA collected and purified to produce medicine
how does MCA help with cancer diagnosis
cancerous cells have antigens so monoclonal antigens can be designed to be complementary and they will bind and clump the cells together
how does this help
it will be easier to identify where a tumour is so it can be removed
what else can MCA do(2)
1) carry toxic drugs to tumour to stop growth
2) encourage immune system to attack cancer cells directly
other diseases that MCA can help identify ?
HIV
AIDS
