What are polyclonal antibodies?

St John's Laboratory lists tens of thousands of polyclonal antibodies, produced across a range of host species.

  • Multiple epitopes, one antigen Because polyclonal antibodies come from multiple B-cell lineages, they react against a specific antigen across a variety of different epitopes rather than a single binding site.
  • Broader signal detection Binding multiple epitopes on the same target can give a stronger overall signal compared with a single-epitope monoclonal antibody.
  • A wide range of host species St John's Laboratory offers 40,796 polyclonal antibodies across a range of host species, including goat, rabbit, chicken, and guinea pig.
Production process

How polyclonal antibodies are made
