During the immune reaction, antigen-processing cells activate quiescent B-cells into plasmocytes to secrete immunoglobulins directed against that antigen. Each plasmocyte produces immunoglobulins that are specific for one epitope of a given antigen. Polyclonal antibodies are composed of a mix of immunoglobulins secreted by multiple plasmocytes clones, and thus recognise multiple epitopes on one antigen.


From the multiple plasmocytes clones involved in the immune reaction, each one can be isolated from the others by common cell culture techniques. Once isolated, this cell and its descendants produce identical immunoglobulins of the same subtype. These immunoglobulins are then called monoclonal antibodies, and share the same affinity and specificity for one single epitope of the desired antigen.

If you have difficulties choosing between polyclonal or monoclonal, you can browse our Polyclonal Vs. Monoclonal section.
