Iga: usually found in body fluids, tears, saliva, milk, etc. It is made out of two of the y structures therefore it is more efficient in binding the bacteria. Igm: even more complicated, there are 5 molecules joined together that gives them 10 binding sites. Ige: often involved in hypersensitivity and allergic reactions no two b cells are identical.
