True. Antibody cross-reactivity, where an antibody binds to an epitope on an unintended protein that is structurally similar to its target epitope, is inherently more common with polyclonal antibodies. This is due to their fundamental nature: a polyclonal antiserum contains a heterogeneous mixture of antibodies produced by many different B-cell clones in an immunized animal. While the majority are against the immunogen, the animal's immune system can also generate antibodies against minor contaminants in the immunogen preparation or against epitopes shared between the target and unrelated proteins. This increases the risk of non-specific binding. Monoclonal antibodies, being derived from a single B-cell clone, are homogeneous and recognize a single, specific epitope. This provides much higher specificity and lower risk of cross-reactivity, although it is not absolute—some monoclonal antibodies can still cross-react if their unique epitope is shared by another protein. Therefore, for critical diagnostic applications demanding high specificity, well-validated monoclonal antibodies are generally preferred.
