Question:

What portion of a secondary antibody bind to on a primary antibody?

Danny S.
Answer:

antibodies are made up of two major pats. The Fc chain is species specific and the variable chain is epitope specific. Primary binds to a specific epitope on a structure or protein. Secondary antibodies are produced against the Fc region and are only specific to an animal's Fc region. Secondary antibodies often contain a color metric or fluorescent signal that indicates the presence of the primary antibody. Variable chains from secondaries can bind to specific animal Fc chain epitopes. For example, for a researcher may use a primary rabbit antibody bound to horseradish peroxidase (rabbit anti-HRP), then the researcher will us secondary with a color metric or fluorescence tag such as a mouse antibody against rabbit (mouse anti-rabbit). This would mean that the variable region of mouse anti-body would bind to the Fc chain of the rabbit antibody.
