Labs that do a lot of Western blots often have hundreds of primary bodies but only two or three secondary antibodies. Why? I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.

Immune Disorders

The collaboration between the cells and proteins that work together as a defense system against infection comprises the immune system.Each of them performs a variety of tasks to recognize and/or react against a foreign body.
