Question

Welcome to Openstudy ^_^ Antibodies are a kind of protein that gets secreted by B lymphocytes of the immune system, and each antibody is going to be specific to one epitope. Once the antibody finds its specific target, such as the surface of a pathogenic bacteria, other cells in the immune system will perform a certain function depending on the kind of antibody.
