All of the following are true with respect to IgM antibodies EXCEPT which one A.

A microscope that uses antibodies that glow to reveal the location of a protein in a cell is the. Antibodies are not formed against cancer cells. Thus assays that measure antibody function are differentiated from those that strictly measure the ability of an antibody to bind to its cognate antigen.

Antibodies have a variable region that binds antigen. Cytotoxic T cells react with tumor specific antigens. If those antibodies are not present either the person is not infected or the infection occurred a very long time ago and the B cells generating these specific antibodies have naturally decayed.
