There are five classes of antibody.
1) <span>IgA (immunoglobin A)
2) IgD (immunoglobin D)
3) IgE (immunoglobin E)
4) IgG (immunoglobin G)
<span>5) IgM (immunoglobin M)
They form Y shaped antibodies. The crystallized fragment is the stalk of the Y shaped antibodies. The bond formed by this stalk will determine the form of the antibody. One Y is called monomer, two connected Ys are called dimers, and 5 connected Ys are called pentamers.</span></span>
In an experiment, using the elodea stalk, you are able to expose more underlying tissue and the process can be executed more quickly and it's easy to replicate the natural position for a more realistic result.
hope this helps
look at the photo, it wouldn't let me type it, sorry :-/
